Question

Solve the following equation by first writing the equation in the form ax^2=c 15+c^2=96

Answer 1

t^2 - 49 =0
t^2=49
t=7 or t=-7

Answer 2

Answer:

The solution of the equation is:

               $c=\pm 9$

Step-by-step explanation:

The quadratic equation here in terms of the variable c is given by:

                    $15+c^2=96$

Now on subtracting 15 from both the sides of the equation we have:

$15+c^2-15=96-15\\\\15-15+c^2=81\\\\0+c^2=81\\\\c^2=81$

Hence, on comparing the equation with:

$ax^2=c$

we have:

$a=1\ and\ c=81$

Now on taking the square root on both the sides of the equation we have:

              $c=\pm 9$
