Question

Factorization of 2x (to the 2nd power) + x-15

Answer 1

\[ 2x^{2}+x-15\] what have you tried so far?

Answer 2

Yes

Answer 3

2x^2+x-15
Multiplies to be -30, adds up to be 1.
2x^2+6x-5x-15
(2x^2+6x)(-5x-15)
2x(x+3)-5(x+3)
(2x-5)(x+3)=0
x=-3 x=5/2

Answer 4

Correct thank you

Answer 5

Factorization of -X^2 +3x +28

Answer 6

Try it on your own first

Answer 7

-(x^2-3x-28)
Then find the numbers that multiply to be -28 and add to be -3.

Answer 8

correct, what have you got so far?

Answer 9

4 and -7 are your factors.
So -1(x+4)(x-7)=0
