Question

Which of the following are solutions to the quadratic equation below?
x2 + 10x + 25 = 2

Answer 1

first you want to factor it out, so think of two numbers that when added together equal 10 and when multiplied together equal 25

Answer 2

\[\begin{align}
x^2+10x+25&=2\\
(x+5)^2&=2\\
x+5&=\pm\sqrt{2}\\
x&=\pm\sqrt{2}-5

\end{align}\]
