Question 584486: Can you help me factor each of the following quadratics if possible.'
A) x(to the second power)+3x-10.
C)x (to the sencond power) +3x+10
D) x(to the second power)-10x+24
Answer by ianhq(1) (Show Source): You can put this solution on YOUR website!
A)x^2+3x-10
1)find 2 factors of negeative ten that add to 3. If there are none then solve the unfactorable by doing this:
A1)make it a binomial ie. x^2+3x=10
A2)find a c value by dividing 3/2 and squaring it. ie. x^2+3x+3/2^2=10 and then doing that to get x^2+3x+9/4=10
A3)make it a sq. Binomial ie. (x+3/2)^2=10
A4) solve it ie.x=-3/2 plus or minus the square root of 10.
If you can get that you can get them all. Good luck!
