## anonymous one year ago Solve 2x2 = 50. A. {±5} B. {±25} C. {±6} D. {±12.5}

Step 1: Divide both sides by 2 $\frac{ 2x^2 }{ 2 } = \frac{ 50 }{ 2 }$ Which equals: $x^2 = 25$

2. KendrickLamar2014

Step 2. Take the Square Root of 25: $x = \pm \sqrt{25}$ Which equals: $x = 5 ~or~ x = -5$

$Answer: \pm 5$
