Solution for 8y^2-[-8y-(-10y^2+9y)]-[6+(-11y-6)]= equation:


Simplifying
8y2 + -1[-8y + -1(-10y2 + 9y)] + -1[6 + (-11y + -6)] = 0

Reorder the terms:
8y2 + -1[-8y + -1(9y + -10y2)] + -1[6 + (-11y + -6)] = 0
8y2 + -1[-8y + (9y * -1 + -10y2 * -1)] + -1[6 + (-11y + -6)] = 0
8y2 + -1[-8y + (-9y + 10y2)] + -1[6 + (-11y + -6)] = 0

Combine like terms: -8y + -9y = -17y
8y2 + -1[-17y + 10y2] + -1[6 + (-11y + -6)] = 0
8y2 + [-17y * -1 + 10y2 * -1] + -1[6 + (-11y + -6)] = 0
8y2 + [17y + -10y2] + -1[6 + (-11y + -6)] = 0

Reorder the terms:
8y2 + 17y + -10y2 + -1[6 + (-6 + -11y)] = 0

Remove parenthesis around (-6 + -11y)
8y2 + 17y + -10y2 + -1[6 + -6 + -11y] = 0

Combine like terms: 6 + -6 = 0
8y2 + 17y + -10y2 + -1[0 + -11y] = 0
8y2 + 17y + -10y2 + -1[-11y] = 0

Remove brackets around [-11y]
8y2 + 17y + -10y2 + -1 * -11y = 0

Multiply -1 * -11
8y2 + 17y + -10y2 + 11y = 0

Reorder the terms:
17y + 11y + 8y2 + -10y2 = 0

28y + 8y2 + -10y2 = 0

Combine like terms: 8y2 + -10y2 = -2y2
28y + -2y2 = 0

Solving
28y + -2y2 = 0

Solving for variable 'y'.

Factor out the Greatest Common Factor (GCF), '2y'.
2y(14 + -1y) = 0

Ignore the factor 2.

Subproblem 1

Set the factor 'y' equal to zero and attempt to solve: Simplifying y = 0 Solving y = 0 Move all terms containing y to the left, all other terms to the right. Simplifying y = 0

Subproblem 2

Set the factor '(14 + -1y)' equal to zero and attempt to solve: Simplifying 14 + -1y = 0 Solving 14 + -1y = 0 Move all terms containing y to the left, all other terms to the right. Add '-14' to each side of the equation. 14 + -14 + -1y = 0 + -14 Combine like terms: 14 + -14 = 0 0 + -1y = 0 + -14 -1y = 0 + -14 Combine like terms: 0 + -14 = -14 -1y = -14 Divide each side by '-1'. y = 14 Simplifying y = 14

Solution

y = {0, 14}
