If this is your equation: Solution: LCD for 5 and 5x is 5x ←cross product 20x + 30 = 5x² + 25x ←simplify with distributive property 0 = 5x² + 5x - 30 ←use inverse operations to collect all terms on one side 0 = x² + x - 6 ←if possible divide by numerical GCF (This case 5) 0 = (x + 3)(x - 2) ←Factor x = -3 or x = 2 Please check by substitution in original equation... Both work
