Answer:
2x^3 + 2x^2 - 10x
Explanation:
Order of operations is the system which defines how to simplify an expression. It states PEMDAS or parenthesis, exponents, multiplication, division, addition and subtraction, though some operations are related as such like MD and AS and can be done in any order left to right.Using this order, simplify inside the parenthesis first.
2x (x*x + x - 5)
2x (x^2 + x -5)
Now, multiply into the parenthesis using the distributive property. Multiply each term by 2x.
2x^3 + 2x^2 - 10x
