How to Evaluate Variable Expressions with Integers | Minute Math

In this video we cover how to evaluate variable expressions with integers. We are given the variable expression 4x^2-2xy+3y^2 when x=2, y=-1. We use this information to simplify this variable expression but substituting the x and y value and simplifying the expression using PEMDAS. #PEMDAS #variableexpression #minutemath #simplify #variable #expression #mathhelp #onlinemathvideos #lightboard #math #mathvideos
