Write an expression that is equivalent to 2x2 - 2x + 7?

11-2x

We need to solve this using PEMDAS

P-Parentheses
E-exponents
M-multiplication
D-division
A-addition
A-subtraction

Let’s rewrite the equation

2•2-2x+7

The first thing we see here (in the order of PEMDAS) is multiplication. Let’s multiply 2•2

4-2x+7

The next thing we see here (in the order of PEMDAS) is addition. Let’s add 4 and 7.

11-2x

We cannot simplify this anymore since -2x has a variable with it. Your final equation will be 11-2x, which is still equivalent to your original expression.
