Solution for (3+y)(4y-7)=0 equation:


Simplifying
(3 + y)(4y + -7) = 0

Reorder the terms:
(3 + y)(-7 + 4y) = 0

Multiply (3 + y) * (-7 + 4y)
(3(-7 + 4y) + y(-7 + 4y)) = 0
((-7 * 3 + 4y * 3) + y(-7 + 4y)) = 0
((-21 + 12y) + y(-7 + 4y)) = 0
(-21 + 12y + (-7 * y + 4y * y)) = 0
(-21 + 12y + (-7y + 4y2)) = 0

Combine like terms: 12y + -7y = 5y
(-21 + 5y + 4y2) = 0
