Question

The root of *x^2 = 16 areOption 1 [ +4 ]+4(0,4)-4​

Answer 1

Answer:

The roots of the equation are

- 4 and 4

Step-by-step explanation:

First rewrite the expression

That's

x² - 16

16 = 4²

So we have

x² - 4² = 0

Using the identity

a² - b² = (a + b)(a - b)

Rewrite the expression

So we have

x² - 4² = 0 is

( x + 4)( x - 4) = 0

x + 4 = 0 x - 4 = 0

x = - 4 x = 4

The roots of the equation are

- 4 and 4
