Question

x^2+5x=(-3)^2+5 (-3)+6=-9-15=-24 substitute x=-3?

Answer 1

(-3)^2+5(-3)=9+(-15)
=9-15=-6

Answer 2

Hey friend, Harish here.

Here is your answer.

Given expression..  → x² + 5(x) 

Value of  x = (-3)

Therefore the value of the equation when we substitute x = -3 is:

(-3)² + 5(-3) =  9 - 15 = - 6

So, the value of x² + 5x = -6.
