The root of *x^2 = 16 areOption 1 [ +4 ]+4(0,4)-4
1 answer:
Answer:
The roots of the equation are
<h3>- 4 and 4</h3>
Step-by-step explanation:
First rewrite the expression
That's
x² - 16
16 = 4²
So we have
x² - 4² = 0
Using the identity
<h3>a² - b² = (a + b)(a - b)</h3>
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
