Question

Can you tell me in steps how to solve this quadratic formula problem?It's for an essay

Answer 1

`\begin{gathered} x_(1,2)=\frac{-(2)\pm\sqrt[]{(2)^2-4(2)(-12)}}{2(2)} \\ x_(1,2)=\frac{-2\pm\sqrt[]{4-(-96)}}{4}\text{ Solving the multiplications, the square and removing parentheses} \\ x_(1,2)=\frac{-2\pm\sqrt[]{100}}{4}\text{ Solving the subtraction} \\ x_(1,2)=(-2\pm10)/(4)\text{ Solving the square root} \\ Now,\text{ we have two solutions, the first one considers the plus symbol:} \\ x_1=(-2+10)/(4)=(8)/(4)=2 \\ \text{The second solution considers the minus symbol:} \\ x_2=(-2-10)/(4)=(-12)/(4)=-3 \end{gathered}`
