Answer: 4

Step-by-step explanation: when finding the difference you're subtracting the 2 so 8-4=4 9x^2 + 5x - 6= 8

Factoring 9x2+5x-6

The first term is, 9x2 its coefficient is 9 .

The middle term is, +5x its coefficient is 5 .

The last term, "the constant", is -6

Step-1 : Multiply the coefficient of the first term by the constant 9 • -6 = -54

Step-2 : Find two factors of -54 whose sum equals the coefficient of the middle term, which is 5 .

-54 + 1 = -53

-27 + 2 = -25

-18 + 3 = -15

-9 + 6 = -3

-6 + 9 = 3

-3 + 18 = 15

-2 + 27 = 25

-1 + 54 = 53

=8

2x^2 - 7x + 14 ​=4

actoring 2x2-7x+14

The first term is, 2x2 its coefficient is 2 .

The middle term is, -7x its coefficient is -7 .

The last term, "the constant", is +14

Step-1 : Multiply the coefficient of the first term by the constant 2 • 14 = 28

Step-2 : Find two factors of 28 whose sum equals the coefficient of the middle term, which is -7 .

=4
