i need help with that question
How do you solve 3x squared -9x equals 0?
3x2-9x = 0 x(3x-9) = 0 x = 0 or x = 3
What is the solution of 3x2-9x equals -5?
3x2 - 9x = -5; add 5 to both sides, in order to use the quadratic formula 3x2 - 9x + 5 = 0; a = 3, b = -9, and c = 5 x = [-b ± √(b2 - 4ac)]/(2a) x = {-(-9) ± √[(-9)2 - 4(3)(5)]}/[(2)(3)] = [9 ± √(81 - 60)]/6 = [9 ± √21)/6
