Answer:

Explanation:

(3x + 50)(6x + -10) = 0

Reorder the terms:

(50 + 3x)(6x + -10) = 0

Reorder the terms:

(50 + 3x)(-10 + 6x) = 0

Multiply (50 + 3x) * (-10 + 6x)

(50(-10 + 6x) + 3x * (-10 + 6x)) = 0

((-10 * 50 + 6x * 50) + 3x * (-10 + 6x)) = 0

((-500 + 300x) + 3x * (-10 + 6x)) = 0

(-500 + 300x + (-10 * 3x + 6x * 3x)) = 0

(-500 + 300x + (-30x + 18x2)) = 0

Combine like terms: 300x + -30x = 270x

(-500 + 270x + 18x2) = 0

Solving

-500 + 270x + 18x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '2'.

2(-250 + 135x + 9x2) = 0

Factor a trinomial.

2((-50 + -3x)(5 + -3x)) = 0

Answer:

First of all (3x + 50) is equal to (6x - 10) so (3x + 50) = (6x - 10) 3x + 50 = 6x - 10 60 = 3x 20 = x
