Quadratics Solve by Factoring

Given the factors below what is the quadratic equation?

• y= 2x² -5x +3

• y= 2x² +7x -3

• y= 2x² -5x -3

• y= 2x² -7x -3

Solve by factoring: x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5

Solve by factoring: x² + 3x - 18 = 0

• x = -3 and x = 6

• x = 3 and x = -6

• x = -9 and x = 2

• x = 9 and x = -2

Solve by factoring: 5x² + 13x + 6 = 0

• x = -2 and x = -3/5

• x = 2 and x = 3/5

• x = -2 and x = 3/5

• x = 2 and x = -3/5

81x²=25

• x= 5/9, -5/9

• x= -5/9, -5/9

• x= 5/9, 5/9

Factor and Solve: Remember the two numbers you choose when factoring, are not your solutions to the equation!
