Use the substitution method

F(-2)=x^2-3

=(-2)^2-3

Use PEMDAS

P= parenthesis

E= exponents

M=multiplication

D=division

A=addition

S=subtraction

Do (-2)^2 first then -3

Put down (-2)(-2) two times because of the exponent

-negative number * -negative number= +positive number

4-3

What is the simplified expression for the expression below?
Alika [10]
We have the expression 4(x + 8) + 5(x - 3).
First, expand the parentheses by using the distributive property.

4(x + 8) + 5(x - 3) = 4x + 32 + 5x - 15

Now combine like terms.

4x + 32 + 5x - 15 = 9x + 17

So, C 9x + 17 is the answer.
