Question 854247: Could you please help me with this question please..Thank you so much
Expand all terms in each of the following expressions. Where possible, simplify the result by collecting like terms.
a.)(6y-x)(2x+3)
b.)x(x+3y)-y(3x-y)-(-x^2+y^2) Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Expand all terms in each of the following expressions. Where possible, simplify the result by collecting like terms.
a.)(6y-x)(2x+3)
FOIL
12xy + 18y - 2x^2 - 3x
:
b.)x(x+3y)-y(3x-y)-(-x^2+y^2)
multiply, remove the brackets, change the signs.
x^2 + 3xy - 3xy + y^2 + x^2 - y^2
Combinelike terms
x^2 + x^2 + y^2 - y^2 + 3xy - 3xy
leaving just
2x^2
