Ax2 + bx + c
Factor the trinomial 7x2 – 3x – 4.
Which pair of numbers has a product of ac and a sum
of b?
ac
What is the factored form of the trinomial?

(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 :

                      =

                      =

if x decreases by 4 then y increases by 10

its c or d   take a lucky guess my dude
