Question

How do you convert y=2(x-5)(x+2) into standard form, y=ax^2+bx+c?

Answer 1

Multiply it.

Answer 2

so would i do 2(x-5) 2(x+2) ?

Answer 3

hi

Answer 4

2(x^2-5x+2x-10)=2x^2-2*3x-10=0
2x^2-6x-10

Answer 5

y=2x^2-6x-10

Answer 6

y=2(x-5)(x+2)
y=(2x-10)(x+2)
y=2x(x+2)-10(x+2)
\[y=2x^2+4x-10x-20 =2x^2-6x-20\] which is in the form of y=ax^2+bx+c

@ali1029

Answer 7

so it would be 2x^2-6x-20 and not 2x^2-6x-10 ?

Answer 8

Yes, it would be 2x^2-6x-20

Answer 9

2x^2−6x−20

Answer 10
