# Chapter 8 - Section 8.2 - Solving Quadratic Equations by the Quadratic Formula - Exercise Set: 75b

The given set of values is the correct substitution for $a, b,$ and $c$ in the standard form $ax^2+bx+c=0$.

#### Work Step by Step

RECALL: The standard form of a quadratic equation is $ax^2+bx+c=0$ Write the given quadratic in equation in standard form to obtain: $x^2=-10 \\x^2+10=-10+10 \\x^2+10=0$ The quadratic equation above has: $a=1, b=0, c=10$ Thus, the given set of values is the correct substitution for $a, b,$ and $c$ in the standard form $ax^2+bx+c=0$.
