Answer:
1. x=4√3
≈6.92820323
x=−4√3
≈−6.92820323
2. x=3/2=1 1/2
=1.5
x=−3/2 =−1 1/2
=−1.5
Step-by-step explanation:
1. x^2 = 48
Take the square root of both sides of the equation.
x=4√3
x=−4√3
2. 4x^2 – 9= 0
Add 9 to both sides. Anything plus zero gives itself.
4x^2 = 9
Divide both sides by 4.
x^2=9/4
Take the square root of both sides of the equation.
x=3/2
x=−3/2
