25X + 30 = 15X
subtract 15X from each side
25X - 15X + 30 = 15X - 15X
10X + 30 = 0
subtract 30 from each side
10X + 30 - 30 = 0 - 30
10X = -30
divide both sides integers by 10
(10/10)X = - 30/10
X = - 3

5x2 + 25x + 30 This expression describes a parabola, and can be factored out as follows: = 5(x2 + 5x + 6) = 5(x + 2)(x + 3)
5 xto the power 2-25x plus 30 equals?
This is a quadratic equation in the form of: 52 - 25x + 30 = 0 Solve by using the quadratic equation formula: x = 2 or x = 3 Or by factorising: (5x-10)(x-3) = 0, which means that x = 10/5 or x = 3
12 is added to 25 percent of a number and equals 30 what is the number?
