Question

4 (x2 + 7x + 12) = (2x + 6) polynomial by polynomial​

Answer 1

Question:

$4(x^2+7x+12)=(2x+6)$ Solve the given equation

Answer:

$-167$

Step-by-step explanation:

Given:

We have to solve the equation into simpler form

⇒$4(x^2+7x+12)=(2x+6)$

⇒$(4*x^2+4*7x+4*12)=(2x+6)$

⇒$4x^2+28x+48=2x+6$

Let us change 2x+6 into Left Side so that we can add/Sub the equation

⇒$4x^2+28x-2x+48-6=0$

⇒$4x^2+26x+42=0$

We can see that everything can be divided by 2 so let us divide

⇒$2x^2+13x+42$

We can use the formula$(b^2-4ac)$

⇒ A = 2

⇒ B = 13

⇒  C = 42

Let us Substitute in the formula

⇒ $13^2-4(2)(42)$

⇒ $169-336$

⇒$-167$

Hence your answer is -167

Formula Used in the Sum : $(b^2-4ac)$
