Answer:
-26
Step-by-step explanation:
a = -2 and b = -3, evaluate a(a² + b²)
= -2(-2²+-3²)
= -2(4+9)
= -2(13)
= -26
Answer: -26
Step-by-step explanation:
Concept:
When encountering questions that gave you numbers that stand for each variable and require an evaluation, it is basically substituting the numbers back to the given expression.
Solve:
a = -2, b = -3
Given
a (a² + b²)
Substitute numbers
=(-2) [(-2)² + (-3)²]
Simplify exponents inside the bracket
=(-2) [ 4 + 9]
Addition inside the bracket
=(-2) [13]
Simplify through multiplication
=-26
