Factoring

100

Factor x² + 7x -18 and solve for x. 

x = -9, 2

200

Factor 2x² + 9x - 18 and solve for x.

x = 3/2, -6

300

Factor by grouping and solve for x. 

2x³ - x² - 8x + 4 = 0 

x = 1/2, 2, -2

400

PSYCHE. Solve for x using the quadratic equation. 

2x² - 3x -4

(3 +- sqrt(41))/4

500

Factor and solve for x. 

5x³ - 14x² - 3x

x = -1/5, 3, 0
