The given trinomial can be factored using the factorization method.

x² + 15x + 56
= x² +8x +7x + 56
= x(x+8) + 7(x+8)
= (x+8)(x+7)

Thus, (x+8)(x+7) is the factored form of the polynomial.

So the correct answer is option B

What are the solution(s) to the quadratic equation 9x2 = 4?

Kaylis [27]

Answer:

Option B.

Step-by-step explanation:

The given quadratic equation is

$9x^2=4$

We need to find the solution of given quadratic equation.

Divide both sides by 9.

$\frac{9x^2}{9}=\frac{4}{9}$

$x^2=\frac{4}{9}$

Taking square root on both sides.

$x=\pm\sqrt{\frac{4}{9}}$

$x=\pm\frac{2}{3}$

The solution of given equation are $x=\frac{2}{3}$ and $x=-\frac{2}{3}$ .

Therefore, the correct option is B.
