9x3 plus 27x2 - 90x?
As long as the equation is 9x3 + 27x2 - 90x = 0, the answer is : 27 + 27x2 - 90x = 0 9x3 = 27 27 + 54 - 90x = 0 27x2 = 54 81 - 90x = 0 27 + 54 = 81 81 = 90x add 90x to each side 9/10 = x divide each side by 90 x = .9
What is the quotient of 84 and x?
90x
Solve the equation by factoring 15 equals 8x2-14x?
15 = 8x2 - 14x; whence, 8x2 - 14x - 15 = (2x - 5)(4x + 3) = 0. Therefore, x = 5/2 or -3/4.
