Step-by-step explanation:

a = -2 and b = -3, evaluate a(a² + b²)

= -2(-2²+-3²)

= -2(4+9)

= -2(13)

= -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
