Solution for =a*(x-6)*(x-7)*(x-b) equation:


Simplifying
0 = a(x + -6)(x + -7)(x + -1b)

Reorder the terms:
0 = a(-6 + x)(x + -7)(x + -1b)

Reorder the terms:
0 = a(-6 + x)(-7 + x)(x + -1b)

Reorder the terms:
0 = a(-6 + x)(-7 + x)(-1b + x)

Multiply (-6 + x) * (-7 + x)
0 = a(-6(-7 + x) + x(-7 + x))(-1b + x)
0 = a((-7 * -6 + x * -6) + x(-7 + x))(-1b + x)
0 = a((42 + -6x) + x(-7 + x))(-1b + x)
0 = a(42 + -6x + (-7 * x + x * x))(-1b + x)
0 = a(42 + -6x + (-7x + x2))(-1b + x)

Combine like terms: -6x + -7x = -13x
0 = a(42 + -13x + x2)(-1b + x)

Multiply (42 + -13x + x2) * (-1b + x)
0 = a(42(-1b + x) + -13x * (-1b + x) + x2(-1b + x))
0 = a((-1b * 42 + x * 42) + -13x * (-1b + x) + x2(-1b + x))
0 = a((-42b + 42x) + -13x * (-1b + x) + x2(-1b + x))
0 = a(-42b + 42x + (-1b * -13x + x * -13x) + x2(-1b + x))
0 = a(-42b + 42x + (13bx + -13x2) + x2(-1b + x))
0 = a(-42b + 42x + 13bx + -13x2 + (-1b * x2 + x * x2))
0 = a(-42b + 42x + 13bx + -13x2 + (-1bx2 + x3))

Reorder the terms:
0 = a(-42b + 13bx + -1bx2 + 42x + -13x2 + x3)
0 = a(-42b + 13bx + -1bx2 + 42x + -13x2 + x3)
0 = (-42b * a + 13bx * a + -1bx2 * a + 42x * a + -13x2 * a + x3 * a)
0 = (-42ab + 13abx + -1abx2 + 42ax + -13ax2 + ax3)

Solving
0 = -42ab + 13abx + -1abx2 + 42ax + -13ax2 + ax3

Solving for variable 'a'.

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