Answer 1

Answer:

x=-2 or x=-3 is the answer

Answer 2

Answer:

$\Large\boxed{X=-2, \quad X=-3}$

Step-by-step explanation:

GIVEN:

To solve this problem, first you have to use quadratic equation formula. Isolate by the x on one side of the equation.

SOLUTIONS:

First, used quadratic equation formula.

$\Large\boxed{\textnormal{QUADRATIC EQUATIONS FORMULA}}}$

$\displaystyle\frac{-B\pm \sqrt{B^2-4AC}}{2A}$

A=1

B=5

C=6

Rewrite the problem down.

$\displaystyle\frac{-5\pm \sqrt{5^2-4* 1*6}}{2* 1}$

Solve.

$\displaystyle -5+\sqrt{5^2-4*\:1*\:6}=-4$

$\displaystyle \frac{-4}{2*1}$

Multiply.

$\displaystyle 2*1=2$

$\displaystyle \frac{-4}{2}=-\frac{4}{2}$

Divide.

$\displaystyle 4\div2=2$

$\Large\boxed{X=-2}$

$\displaystyle \frac{-5-\sqrt{5^2-4* \:1* \:6}}{2* \:1}$

Solve.

$-5-\sqrt{5^2-4* \:1* \:6}=-6$

$\displaystyle \frac{-6}{2*1}$

Multiply.

$\displaystyle 2*1=2$

$\displaystyle \frac{-6}{2}=-\frac{6}{2}$

Divide.

$\displaystyle 6\div2=3$

$\Large\boxed{X=-3}$

$\Large\boxed{X=-2, \quad X=-3}$

The correct answer is x=-2, and x=-3.
