Solution for 0=(6y-5)(y+3) equation:


Simplifying
0 = (6y + -5)(y + 3)

Reorder the terms:
0 = (-5 + 6y)(y + 3)

Reorder the terms:
0 = (-5 + 6y)(3 + y)

Multiply (-5 + 6y) * (3 + y)
0 = (-5(3 + y) + 6y * (3 + y))
0 = ((3 * -5 + y * -5) + 6y * (3 + y))
0 = ((-15 + -5y) + 6y * (3 + y))
0 = (-15 + -5y + (3 * 6y + y * 6y))
0 = (-15 + -5y + (18y + 6y2))

Combine like terms: -5y + 18y = 13y
0 = (-15 + 13y + 6y2)

Solving
0 = -15 + 13y + 6y2

Solving for variable 'y'.

Combine like terms: 0 + 15 = 15
15 + -13y + -6y2 = -15 + 13y + 6y2 + 15 + -13y + -6y2

Reorder the terms:
15 + -13y + -6y2 = -15 + 15 + 13y + -13y + 6y2 + -6y2

Combine like terms: -15 + 15 = 0
15 + -13y + -6y2 = 0 + 13y + -13y + 6y2 + -6y2
15 + -13y + -6y2 = 13y + -13y + 6y2 + -6y2

Combine like terms: 13y + -13y = 0
15 + -13y + -6y2 = 0 + 6y2 + -6y2
15 + -13y + -6y2 = 6y2 + -6y2

Combine like terms: 6y2 + -6y2 = 0
15 + -13y + -6y2 = 0
