Solution for 8(z-a)(z-4)= equation:


Simplifying
8(z + -1a)(z + -4) = 0

Reorder the terms:
8(-1a + z)(z + -4) = 0

Reorder the terms:
8(-1a + z)(-4 + z) = 0

Multiply (-1a + z) * (-4 + z)
8(-1a * (-4 + z) + z(-4 + z)) = 0
8((-4 * -1a + z * -1a) + z(-4 + z)) = 0
8((4a + -1az) + z(-4 + z)) = 0
8(4a + -1az + (-4 * z + z * z)) = 0
8(4a + -1az + (-4z + z2)) = 0
8(4a + -1az + -4z + z2) = 0
(4a * 8 + -1az * 8 + -4z * 8 + z2 * 8) = 0
(32a + -8az + -32z + 8z2) = 0

Solving
32a + -8az + -32z + 8z2 = 0

Solving for variable 'a'.

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

Add '32z' to each side of the equation.
32a + -8az + -32z + 32z + 8z2 = 0 + 32z

Combine like terms: -32z + 32z = 0
32a + -8az + 0 + 8z2 = 0 + 32z
32a + -8az + 8z2 = 0 + 32z
Remove the zero:
32a + -8az + 8z2 = 32z

Add '-8z2' to each side of the equation.
32a + -8az + 8z2 + -8z2 = 32z + -8z2

Combine like terms: 8z2 + -8z2 = 0
32a + -8az + 0 = 32z + -8z2
32a + -8az = 32z + -8z2

Reorder the terms:
32a + -8az + -32z + 8z2 = 32z + -32z + -8z2 + 8z2

Combine like terms: 32z + -32z = 0
32a + -8az + -32z + 8z2 = 0 + -8z2 + 8z2
32a + -8az + -32z + 8z2 = -8z2 + 8z2

Combine like terms: -8z2 + 8z2 = 0
32a + -8az + -32z + 8z2 = 0

Factor out the Greatest Common Factor (GCF), '8'.
8(4a + -1az + -4z + z2) = 0

Ignore the factor 8.

Subproblem 1

Set the factor '(4a + -1az + -4z + z2)' equal to zero and attempt to solve: Simplifying 4a + -1az + -4z + z2 = 0 Solving 4a + -1az + -4z + z2 = 0 Move all terms containing a to the left, all other terms to the right. Add '4z' to each side of the equation. 4a + -1az + -4z + 4z + z2 = 0 + 4z Combine like terms: -4z + 4z = 0 4a + -1az + 0 + z2 = 0 + 4z 4a + -1az + z2 = 0 + 4z Remove the zero: 4a + -1az + z2 = 4z Add '-1z2' to each side of the equation. 4a + -1az + z2 + -1z2 = 4z + -1z2 Combine like terms: z2 + -1z2 = 0 4a + -1az + 0 = 4z + -1z2 4a + -1az = 4z + -1z2 The solution to this equation could not be determined.
