(7x+2)(x-3)=0

Solution for (7x+2)(x-3)=0 equation:

Simplifying
(7x + 2)(x + -3) = 0

Reorder the terms:
(2 + 7x)(x + -3) = 0

Reorder the terms:
(2 + 7x)(-3 + x) = 0

Multiply (2 + 7x) * (-3 + x)
(2(-3 + x) + 7x * (-3 + x)) = 0
((-3 * 2 + x * 2) + 7x * (-3 + x)) = 0
((-6 + 2x) + 7x * (-3 + x)) = 0
(-6 + 2x + (-3 * 7x + x * 7x)) = 0
(-6 + 2x + (-21x + 7x2)) = 0

Combine like terms: 2x + -21x = -19x
(-6 + -19x + 7x2) = 0

Solving
-6 + -19x + 7x2 = 0
