Question

Ax2 + bx + c

Answer 1

Answer: (7x + 4)(x - 1)

Step-by-step explanation:

7x^2 - 3x - 4

ax^2 = 7x^2

bx = -3x

c = - 4

4 x -7  =  -28

4 + -7  =  -3

4 and -7 are the number which ahs the product of ac = -28 and b = -3.

factored form : $7x^{2} - 7x + 4x - 4$

                      = $7x(x - 1) + 4(x - 1)$

                      = $(7x + 4)(x - 1)$

Answer 2

Answer:

1. -7 and 4

2. (7x + 4)(x - 1)
