Question

Which of the following are solutions to the equation below?

Check all that apply.

x2 + 10x + 25 = 12

A. x = - - 10
B. x = 2 - 5
C. x = - 10
D. x = -2 - 5
E. x = 12 +
F. x = 12 -

Answer 1

sorry ignore the answer choices

Answer 2

Use the quadratic equation.
\[
x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}
\]
where \(a\) is the coefficient of the term \(x^2\), \(b\) is the coefficient of \(x\) and \(c\) is the constant.

Answer 3

Rearrange the equation into this form first.
\[
ax^2+bx+c=0
\]
Then find a, b and c and use the quadratic equation.

Answer 4

\[\frac{ -10\pm \sqrt{48} }{ 2 }\]
