Answer
-13/3
Work Step by Step
1. Substitute values of p, q, and r into numerator of equation.
-(-4 + 2)^{2} - 3(-10)
First solve parentheses, then exponents, then multiply, then subtract.
-(-2)^{2} - 3(-10) = -4 - 3(-10) = - 4 + 30 = 26
2. Substitute values of p, q, and r into denominator of equation and solve.
2 - 8 = -6
3. Divide numerator by denominator.
26/(-6) = -13/3
