Question

2(2^2x) - 9(2^x) + 4 = 0

Answer 1

Step-by-step explanation:

3.3 Factoring 4x2 - 8x + 9

The first term is, 4x2 its coefficient is 4 .

The middle term is, -8x its coefficient is -8 .

The last term, "the constant", is +9

Step-1 : Multiply the coefficient of the first term by the constant 4 • 9 = 36

Step-2 : Find two factors of 36 whose sum equals the coefficient of the middle term, which is -8 .

-36 + -1 = -37

-18 + -2 = -20

-12 + -3 = -15

-9 + -4 = -13

-6 + -6 = -12

-4 + -9 = -13
