Answer:
x=5 or -5
Step-by-step explanation:
4x^2=100
x^2=25
x=5 or -5
Answer:
x=5 or x=-5
Step-by-step explanation:
To solve this, we need to get x by itself.
4x^2=100
First, we need to get rid of the coefficient: 4. To do this, divide both sides by 4.
4x^2/4=100/4
x^2=25
x is being squared. To get rid of the exponent, take the square root of both sides.
x=5 or x=-5
If we want to check our answer, substitute 5 and -5 in for x
4x^2=100
4(5^2)=100
4(25)=100
100=100
4x^2=100
4(-5^2)=100
4(25)=100
100=100
