Solution for f(x)=a(x-3)(x-8) equation:


Simplifying
f(x) = a(x + -3)(x + -8)

Multiply f * x
fx = a(x + -3)(x + -8)

Reorder the terms:
fx = a(-3 + x)(x + -8)

Reorder the terms:
fx = a(-3 + x)(-8 + x)

Multiply (-3 + x) * (-8 + x)
fx = a(-3(-8 + x) + x(-8 + x))
fx = a((-8 * -3 + x * -3) + x(-8 + x))
fx = a((24 + -3x) + x(-8 + x))
fx = a(24 + -3x + (-8 * x + x * x))
fx = a(24 + -3x + (-8x + x2))

Combine like terms: -3x + -8x = -11x
fx = a(24 + -11x + x2)
fx = (24 * a + -11x * a + x2 * a)
fx = (24a + -11ax + ax2)

Solving
fx = 24a + -11ax + ax2

Solving for variable 'f'.

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

Divide each side by 'x'.
f = 24ax-1 + -11a + ax

Simplifying
f = 24ax-1 + -11a + ax

Reorder the terms:
f = -11a + 24ax-1 + ax
