Factor the polynomial<br> 4x^2 + 12 + 9

Anuta_ua [19.1K]

Answer:

The answer is $(2x+3)^2$ .

Step-by-step explanation:

Multiply the coefficient of the squared term and the constant. Then, find the factors that add up to 12:

$4*9=36\\36:\{1*36,2*18,3*12,4*9,6*6\}\\6+6=12$

Split the middle term:

$4x^2+6x+6x+9$

Factor by grouping:

$[4x^2+6x]+[6x+9]\\2x(2x+3)+3(2x+3)\\(2x+3)(2x+3)\\(2x+3)^2$

If f(x) = 2x2 +

Pavel [41]

Answer:

f(x + 1) = 2x² + 4x + 5

Step-by-step explanation:

Step 1: Plug in (x + 1) in as <em>x</em> in f(x)

f(x + 1) = 2(x + 1)² + 3

Step 2: Expand and distribute

f(x + 1) = 2(x² + 2x + 1) + 3

f(x + 1) = 2x² + 4x + 2 + 3

f(x + 1) = 2x² + 4x + 5
