## Introductory Algebra for College Students (7th Edition)

The expression is evaluated to $39$.
To evaluate the ezpression for $x = -3$, we plug in $-3$ where we see $x$ in the expression: $$(-3)^{2} - 10(-3)$$ Evaluate exponents first, according to order of operations: $$9 - 10(-3)$$ We do the multiplication first: $$9 + 30$$ Finally, we add: $$39$$
