Quadratic equations need different methods from linear equations because adding and dividing terms will not:
AIsolate the variable
BBalance the equation
CChange the constant
DSimplify the fraction
Answer & Solution
Correct answer: A. Isolate the variable
1. Quadratics resist the moves that solve linear equations.
2. Different methods are used to solve quadratic equations than linear equations.
3. Just adding, subtracting, multiplying, and dividing terms will not isolate the variable.
4. Factoring, the square root property and the quadratic formula are needed instead.
