Solution for (a-x)(a-x)=9-x^2 equation:


Simplifying
(a + -1x)(a + -1x) = 9 + -1x2

Multiply (a + -1x) * (a + -1x)
(a(a + -1x) + -1x * (a + -1x)) = 9 + -1x2
((a * a + -1x * a) + -1x * (a + -1x)) = 9 + -1x2

Reorder the terms:
((-1ax + a2) + -1x * (a + -1x)) = 9 + -1x2
((-1ax + a2) + -1x * (a + -1x)) = 9 + -1x2
(-1ax + a2 + (a * -1x + -1x * -1x)) = 9 + -1x2
(-1ax + a2 + (-1ax + 1x2)) = 9 + -1x2
