Solution for P(x)=(2x+5)(x-1) equation: 


Simplifying
P(x) = (2x + 5)(x + -1)

Multiply P * x
xP = (2x + 5)(x + -1)

Reorder the terms:
xP = (5 + 2x)(x + -1)

Reorder the terms:
xP = (5 + 2x)(-1 + x)

Multiply (5 + 2x) * (-1 + x)
xP = (5(-1 + x) + 2x * (-1 + x))
xP = ((-1 * 5 + x * 5) + 2x * (-1 + x))
xP = ((-5 + 5x) + 2x * (-1 + x))
xP = (-5 + 5x + (-1 * 2x + x * 2x))
xP = (-5 + 5x + (-2x + 2x2))

Combine like terms: 5x + -2x = 3x
xP = (-5 + 3x + 2x2)

Solving
xP = -5 + 3x + 2x2

Solving for variable 'x'.

Reorder the terms:
5 + -3x + xP + -2x2 = -5 + 3x + 2x2 + 5 + -3x + -2x2

5 + -3x + xP + -2x2 = -5 + 5 + 3x + -3x + 2x2 + -2x2

Combine like terms: -5 + 5 = 0
5 + -3x + xP + -2x2 = 0 + 3x + -3x + 2x2 + -2x2
5 + -3x + xP + -2x2 = 3x + -3x + 2x2 + -2x2

Combine like terms: 3x + -3x = 0
5 + -3x + xP + -2x2 = 0 + 2x2 + -2x2
5 + -3x + xP + -2x2 = 2x2 + -2x2
