Solution for (5a+2)(6a-1)=a+7a-2 equation:


Simplifying
(5a + 2)(6a + -1) = a + 7a + -2

Reorder the terms:
(2 + 5a)(6a + -1) = a + 7a + -2

Reorder the terms:
(2 + 5a)(-1 + 6a) = a + 7a + -2

Multiply (2 + 5a) * (-1 + 6a)
(2(-1 + 6a) + 5a * (-1 + 6a)) = a + 7a + -2
((-1 * 2 + 6a * 2) + 5a * (-1 + 6a)) = a + 7a + -2
((-2 + 12a) + 5a * (-1 + 6a)) = a + 7a + -2
(-2 + 12a + (-1 * 5a + 6a * 5a)) = a + 7a + -2
(-2 + 12a + (-5a + 30a2)) = a + 7a + -2

Combine like terms: 12a + -5a = 7a
(-2 + 7a + 30a2) = a + 7a + -2

Reorder the terms:
-2 + 7a + 30a2 = -2 + a + 7a

Combine like terms: a + 7a = 8a
-2 + 7a + 30a2 = -2 + 8a

Add '2' to each side of the equation.
-2 + 7a + 2 + 30a2 = -2 + 2 + 8a

Reorder the terms:
-2 + 2 + 7a + 30a2 = -2 + 2 + 8a

Combine like terms: -2 + 2 = 0
0 + 7a + 30a2 = -2 + 2 + 8a
7a + 30a2 = -2 + 2 + 8a

Combine like terms: -2 + 2 = 0
7a + 30a2 = 0 + 8a
7a + 30a2 = 8a
