Solution for (2z+9)(z-7)=y equation: 


Simplifying
(2z + 9)(z + -7) = y

Reorder the terms:
(9 + 2z)(z + -7) = y

Reorder the terms:
(9 + 2z)(-7 + z) = y

Multiply (9 + 2z) * (-7 + z)
(9(-7 + z) + 2z * (-7 + z)) = y
((-7 * 9 + z * 9) + 2z * (-7 + z)) = y
((-63 + 9z) + 2z * (-7 + z)) = y
(-63 + 9z + (-7 * 2z + z * 2z)) = y
(-63 + 9z + (-14z + 2z2)) = y

Combine like terms: 9z + -14z = -5z
(-63 + -5z + 2z2) = y
