exchange x = -2 into your equation like this: 5 + 2*(-2)^2 -3*(-2) you need to equate this utilising the main remarkable order of operations in this order: Parenthesis, Exponents, Multiplication, branch, Addition, Subtraction permit's start up with parenthesis. because of the fact that there are no operations to accomplish interior any of the parenthesis (there is basically a single fee in the two parenthesis consequently) we are able to pass this step. next permit's circulate to the exponent. we've a -2 raised to the potential of two. carry out that next: 5 + 2*4 -3*(-2) next we ought to accomplish multiplication operations. we've a 2 circumstances 4. We relatively have a -thrice a -2. 2 circumstances 4 is 8. -thrice -2 is 6. So our new equation turns into: 5 + 8 + 6 finally carry out addition operations. 5+8+6 = 19. So your answer is nineteen. desire this facilitates! :)
