QUADRATIC WORD PROBLEMS
1 ALGEBRA UNIT 10-SOLVING QUADRATIC EQUATIONS SOLVING QUADRATICS BY FACTORING (DAY 1) HOW TO SOLVE QUADRATIC EQUATIONS: Step 1: Write equation in Standard Form. Step 2: Factor the QUADRATIC equation. Step 3: After the problem has been factored we will complete a step called the T chart. Create a T separating the two ( ). Step 4: Once ( ) are separated, set each ( ) = to 0 and solve for the variable. Step 5: Check each of the roots in the ORIGINAL QUADRATIC equation. 1. Find the roots: 035r12r2 2. Solve for y: 024y11y2 3. Find the zeroes: 06x5x2 4. Solve for y: 28y3y2 QUADRATIC Equation (Standard Form): 2 5. Find the roots: 30xx2 6. Find the zeros: 35w52 7. A plot of land for sale has a width of x ft., and a length that is 8ft less than its width.
