Solution for (a+x)(b-x)=64 equation:


Simplifying
(a + x)(b + -1x) = 64

Multiply (a + x) * (b + -1x)
(a(b + -1x) + x(b + -1x)) = 64
((b * a + -1x * a) + x(b + -1x)) = 64
((ab + -1ax) + x(b + -1x)) = 64
(ab + -1ax + (b * x + -1x * x)) = 64
(ab + -1ax + (bx + -1x2)) = 64
(ab + -1ax + bx + -1x2) = 64

Solving
ab + -1ax + bx + -1x2 = 64

Solving for variable 'a'.

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