Solution for E=2x(3+5x)+8x(7-x)+4(x-1) equation: 


Simplifying
E = 2x(3 + 5x) + 8x(7 + -1x) + 4(x + -1)
E = (3 * 2x + 5x * 2x) + 8x(7 + -1x) + 4(x + -1)
E = (6x + 10x2) + 8x(7 + -1x) + 4(x + -1)
E = 6x + 10x2 + (7 * 8x + -1x * 8x) + 4(x + -1)
E = 6x + 10x2 + (56x + -8x2) + 4(x + -1)

Reorder the terms:
E = 6x + 10x2 + 56x + -8x2 + 4(-1 + x)
E = 6x + 10x2 + 56x + -8x2 + (-1 * 4 + x * 4)
E = 6x + 10x2 + 56x + -8x2 + (-4 + 4x)

Reorder the terms:
E = -4 + 6x + 56x + 4x + 10x2 + -8x2

Combine like terms: 6x + 56x = 62x
E = -4 + 62x + 4x + 10x2 + -8x2

Combine like terms: 62x + 4x = 66x
E = -4 + 66x + 10x2 + -8x2
