Solution for (a+3)(a-3)=a^2+2a-35 equation:


Simplifying
(a + 3)(a + -3) = a2 + 2a + -35

Reorder the terms:
(3 + a)(a + -3) = a2 + 2a + -35

Reorder the terms:
(3 + a)(-3 + a) = a2 + 2a + -35

Multiply (3 + a) * (-3 + a)
(3(-3 + a) + a(-3 + a)) = a2 + 2a + -35
((-3 * 3 + a * 3) + a(-3 + a)) = a2 + 2a + -35
((-9 + 3a) + a(-3 + a)) = a2 + 2a + -35
(-9 + 3a + (-3 * a + a * a)) = a2 + 2a + -35
(-9 + 3a + (-3a + a2)) = a2 + 2a + -35

Combine like terms: 3a + -3a = 0
(-9 + 0 + a2) = a2 + 2a + -35
(-9 + a2) = a2 + 2a + -35

Reorder the terms:
-9 + a2 = -35 + 2a + a2

Add '-1a2' to each side of the equation.
-9 + a2 + -1a2 = -35 + 2a + a2 + -1a2

Combine like terms: a2 + -1a2 = 0
-9 + 0 = -35 + 2a + a2 + -1a2
-9 = -35 + 2a + a2 + -1a2

Combine like terms: a2 + -1a2 = 0
-9 = -35 + 2a + 0
-9 = -35 + 2a
