Question

Solve 6x²-42=0 with the exact values of x

Answer 1

X=-√7 and √7

Explanation:

To solve the equation 6x² - 42 = 0, we can begin by rearranging it to isolate the variable term:

6x² = 42

Then, we can divide both sides by 6:

x² = 7

To get the exact values of x, we need to take the square root of both sides:

x = ±√7

Therefore, the exact values of x are √7 and -√7.
