(y+2)(9y+1)=

Solution for (y+2)(9y+1)= equation:

Simplifying
(y + 2)(9y + 1) = 0

Reorder the terms:
(2 + y)(9y + 1) = 0

Reorder the terms:
(2 + y)(1 + 9y) = 0

Multiply (2 + y) * (1 + 9y)
(2(1 + 9y) + y(1 + 9y)) = 0
((1 * 2 + 9y * 2) + y(1 + 9y)) = 0
((2 + 18y) + y(1 + 9y)) = 0
(2 + 18y + (1 * y + 9y * y)) = 0
(2 + 18y + (1y + 9y2)) = 0

Combine like terms: 18y + 1y = 19y
(2 + 19y + 9y2) = 0

Solving
2 + 19y + 9y2 = 0

0 + y = 0 + -2
y = 0 + -2

Combine like terms: 0 + -2 = -2
y = -2

Simplifying
y = -2
Subproblem 2
Set the factor '(1 + 9y)' equal to zero and attempt to solve:

Simplifying
1 + 9y = 0

Solving
1 + 9y = 0

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

Add '-1' to each side of the equation.
1 + -1 + 9y = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 9y = 0 + -1
9y = 0 + -1

Combine like terms: 0 + -1 = -1
9y = -1

Divide each side by '9'.
