Question #f92a4

Answer 1

In this order: inside the parentheses (already simplified), multiply `1+4z` by `z-2`: `-2+z-8z+(4z^2)`, which is `-2-7z+(4z²)`. So the answer is `1/4x²-7x-2`

Explanation:

You solve it in the order of operations: "Parenthesis, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)", also known as PEMDAS (Please Excuse My Dear Aunt Sally). I already showed you how to solve it in the answer section, so look up there if you're confused. The final step, though, is putting it in order. First the numbers including a variable, an exponent, and a factor, then variables with exponents, then variables with factors, then variables, and finally the leftover numbers.
