Question

I need help whats the answer for 2x^2=50

Answer 1

2x^2=50
/2. /2
X^2=25
To get x alone you have to square root the ^2 to cancel it out , and what you do to one side you must do to the other. This means you also have to square root 25
The square root of x^2 is x and the square root of 25 is 5

The answer is x=5

Answer 2

Answer:

x = 5

x = -5

Step-by-step explanation:

2x^2 = 50

2x^2 - 50 = 0

2(x^2 - 25) = 0

2(x^2 + 5x - 5x - 25) = 0

2((x^2 + 5x) + (-5x - 25)) = 0

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

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

x - 5 = 0

x + 5 = 0

x = 5

x = -5
