Question

Evaluate the following expression.x² + 4x - 9 when x = 5

Answer 1

Okay, here we have this:

Considering the provided expression, we are going to evaluate it in the given value of x, so we obtain the following:

x² + 4x - 9 when x = 5

=(5)² + 4(5) - 9

=25 + 20 - 9

=36

Finally we obtain that x² + 4x - 9 when x = 5 is equal to 36.
