2x^2-27=0 solving quadratic Equations

Question

solving quadratic Equations

Answer 1

Given quadratic equation is 2x^2 - 27 = 0

2x^2 = 27

x^2 = 27/2

x^2 = 13.5

x = sqrt(13.5)

x = 3.67

 

Comments

The equation 2x² - 27 = 0

2x² = 27

x² = 27/2

x²  = 13.5

Apply squre root on each side.

x = ± √(13.5)

x = ± 3.67

Solutions are x = 3.67 and x = -3.67.
