Answer:
-48x^2
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
First, distribute 6 to all terms within the parenthesis.
6(2x + 3) = 12x + 18
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
12x + 18 = 42
First, subtract 18 from both sides.
12x + 18 (-18) = 42 (-18)
12x = 24
Isolate the variable x. Divide 12 from both sides.
(12x)/12 = (24)/12
x = 24/12
x = 2
2 is your answer for x.

Answer:
see explanation
Step-by-step explanation:
(3x - 1)(x + 5)
Each term in the second factor is multiplied by each term in the first factor , that is
3x(x + 5) - 1 (x + 5) ← distribute parenthesis
= 3x² + 15x - x - 5 ← collect like terms
= 3x² + 14x - 5
