Question 477248: Please help me to solve those problems. I would really appreciate any help.Thanks!
1)There is a polynomial which, when multiplied by x^2+2x+3, gives 2x^5+3x^4+8x^3+8x^2+18x+9. What is that polynomial?
2)What are the coordinates of the points where the graphs of f(x) = x^3-x^2 + x + 1 and g(x) = x^3 + x^2 + x-1 intersect?
3)The polynomial f(x) has degree 2. If f(0) =-21, f(1) = -16, and f(2) = -9, then what are the x-intercepts of the graph of f?

Question 477245: Please help me with those problems. Thanks!!!!!
1)Graph x2 + 2xy + y2 = 1.
2)If the parabola de fined by y = ax^2 + 6 is tangent to the line y = x, then calculate the constant a. (A line is tangent to a parabola if it touches the parabola at one point, but is otherwise always "outside" the parabola.)
3)Find a complex number whose square equals i.

Question 477325: Can you please help me solve those problems!! Thank you very much!!!!
1)Let f(x) = x^4 -3x^2 + 2 and g(x) = 2x^4 -6x^2 + 2x -1.
(a) What is the degree of f(x) * g(x)?
(b) Let a be a constant. What is the largest possible degree of f(x) + a * g(x)?
(c) Let b be a constant. What is the smallest possible degree of f(x) + b * g(x)?
2)Find t if the product of x^3 - 4x^2 + 2x - 5 and x^2 + tx - 7 has no x^2 term.
3)Assume that f(3) = 4. Find a point on the graphs of each of the following:
(a) y = f(x) + 4
(b) y = f(x + 1)
(c) y = -2f(2x - 2)
(d) y = (1/2)f( x/2 )
4)Multiplication is commutative because x*y = y *x for all x and y. Multiplication is associative
because x *(y *z) = (x *y) *z. The identity of multiplication is 1, because x*1 = x for all x.
Let a & b = a + ab + b for all a and b.
(a) Is the operation & commutative?
(b) Is the operation & associative?
(c) What number is the identity of &?
(d) What number is the inverse of 3 with respect to &? (Recall that the inverse of 3 with
respect to multiplication is 1/3 because 3 * 1/3 equals the identity of multiplication.)
Thank you very much for your help!!!! I appreciate it a lot!!!!!!! Thanks!!!

Question 479544: Hi there,
Here is the problem and I have the answer, although I'm not understanding how they got the answer: Do the following: (a) Write the equation in slope-intercept form. (b) Give the slope and y-intercept of the line. x=4y-7
(a) Y= 1/4x + 7/4 (How did they get this?)
(b) The slope is 1/4 (Again, how?)
The y-intercept is 7/4 (Again, how?)
Can you break it down step by step so I can understand this??
Thank you so so much!!!

Question 480119: Sue is starting a lawn-cutting business. Her start-up cost to buy two lawn mowers and an edge trimmer is $665. She has figured out that she will use about $1 in gas for each lawn. If she charges $20 per lawn, what will her break-even point be?
I have to use the substitution method to solve it
But I am having trouble trying to figure out the two equations
I think one equation might be 2x+t=665
