Solve each equation by finding square roots if the equation has no real number solution right no solution 4g^2=25

slavikrds [6]

ANSWER

$g = - \frac{5}{2} \: or \: g = \frac{5}{2}$

EXPLANATION

The given equation is

$4 {g}^{2} = 25$

Divide both sides by 4.

${g}^{2} = \frac{25}{4}$

Take the square root of both sides:

$g = \pm \sqrt{ \frac{25}{4} }$

$g = \pm \frac{5}{2}$

Split the plus or minus sign:

$g = - \frac{5}{2} \: or \: g = \frac{5}{2}$
