Can someone help me with this asap (algerbra)

Answer 1

PEMDAS

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis, Exponents (& Roots), Multiplication, Division, Addition, Subtraction.

First, divide 3 from both sides of the equation:

$\frac{(3x^2)}{3} = \frac{(48)}{3}$

$x^{2} = \frac{48}{3}\\ \\x^2 = 16$

Next, isolate the variable, x, by rooting both sides of the equation:

$\sqrt{x^{2} } = \sqrt{16}\\ x = \sqrt{16} = \sqrt{4 * 4}$

x = ±4

C) ±4 is your answer.
