(x-21)(x+14)=y

Solution for (x-21)(x+14)=y equation:

Simplifying
(x + -21)(x + 14) = y

Reorder the terms:
(-21 + x)(x + 14) = y

Reorder the terms:
(-21 + x)(14 + x) = y

Multiply (-21 + x) * (14 + x)
(-21(14 + x) + x(14 + x)) = y
((14 * -21 + x * -21) + x(14 + x)) = y
((-294 + -21x) + x(14 + x)) = y
(-294 + -21x + (14 * x + x * x)) = y
(-294 + -21x + (14x + x2)) = y

Combine like terms: -21x + 14x = -7x
(-294 + -7x + x2) = y

Solving
-294 + -7x + x2 = y

Solving for variable 'x'.

Combine like terms: y + -1y = 0
-294 + -7x + x2 + -1y = 0
