Question

State the steps on how to solve 5x2 – 18 = 27 using Square root Property in solving Quadratic Equation.

Answer 1

Answer: x = 3

Step-by-step explanation:

From the question,

5x² – 18 = 27

Collect the like terms

5x² = 27 + 18

5x² = 45

We can th n divide both side by 5 which is the coefficient of x²

5x²/5 = 45/5

x² = 9

To get the value of x, we find the square root of 9

x² = 9

x =✓9

x = 3

The value of x is 3
