Solution for 0=(x-3)(x^2-px+q) equation:


Simplifying
0 = (x + -3)(x2 + -1px + q)

Reorder the terms:
0 = (-3 + x)(x2 + -1px + q)

Reorder the terms:
0 = (-3 + x)(-1px + q + x2)

Multiply (-3 + x) * (-1px + q + x2)
0 = (-3(-1px + q + x2) + x(-1px + q + x2))
0 = ((-1px * -3 + q * -3 + x2 * -3) + x(-1px + q + x2))
0 = ((3px + -3q + -3x2) + x(-1px + q + x2))
0 = (3px + -3q + -3x2 + (-1px * x + q * x + x2 * x))
0 = (3px + -3q + -3x2 + (-1px2 + qx + x3))

Reorder the terms:
0 = (3px + -1px2 + -3q + qx + -3x2 + x3)
0 = (3px + -1px2 + -3q + qx + -3x2 + x3)

Solving
0 = 3px + -1px2 + -3q + qx + -3x2 + x3

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-3px' to each side of the equation.
0 + -3px = 3px + -1px2 + -3q + qx + -3x2 + -3px + x3
Remove the zero:
-3px = 3px + -1px2 + -3q + qx + -3x2 + -3px + x3

Reorder the terms:
-3px = 3px + -3px + -1px2 + -3q + qx + -3x2 + x3

Combine like terms: 3px + -3px = 0
-3px = 0 + -1px2 + -3q + qx + -3x2 + x3
-3px = -1px2 + -3q + qx + -3x2 + x3

Add 'px2' to each side of the equation.
-3px + px2 = -1px2 + -3q + qx + -3x2 + px2 + x3

Reorder the terms:
-3px + px2 = -1px2 + px2 + -3q + qx + -3x2 + x3

Combine like terms: -1px2 + px2 = 0
-3px + px2 = 0 + -3q + qx + -3x2 + x3
-3px + px2 = -3q + qx + -3x2 + x3

Reorder the terms:
-3px + px2 + 3q + -1qx + 3x2 + -1x3 = -3q + 3q + qx + -1qx + -3x2 + 3x2 + x3 + -1x3

Combine like terms: -3q + 3q = 0
-3px + px2 + 3q + -1qx + 3x2 + -1x3 = 0 + qx + -1qx + -3x2 + 3x2 + x3 + -1x3
-3px + px2 + 3q + -1qx + 3x2 + -1x3 = qx + -1qx + -3x2 + 3x2 + x3 + -1x3

Combine like terms: qx + -1qx = 0
-3px + px2 + 3q + -1qx + 3x2 + -1x3 = 0 + -3x2 + 3x2 + x3 + -1x3
-3px + px2 + 3q + -1qx + 3x2 + -1x3 = -3x2 + 3x2 + x3 + -1x3

Combine like terms: -3x2 + 3x2 = 0
-3px + px2 + 3q + -1qx + 3x2 + -1x3 = 0 + x3 + -1x3
-3px + px2 + 3q + -1qx + 3x2 + -1x3 = x3 + -1x3

Combine like terms: x3 + -1x3 = 0
-3px + px2 + 3q + -1qx + 3x2 + -1x3 = 0
