Question

Find the value of c such that the equation x^2 - c = 0 has 12 and –12 as solutions.

Answer 1

Answer:

c=144

Step-by-step explanation:

The given equation is $x^2-c=0$

If this equation has 12 and -12 as roots, then the roots must satisfy the equation.

We substitute x=12 to obtain

$12^2-c=0$

$144-c=0$

Solve for c to get:

$144=c$

This implies that:

$c=144$

We could have also substitute x=-12 to get the same result.
