See explanation

Step-by-step explanation:

Let the given equation be:

$5 {x}^{2} - 400 = 0$

This implies that:

$5 {x}^{2} = 400$

Divide through by 5 to get;

${x}^{2} = 80$

Take square root to obtain:

$x = \pm \sqrt{80}$

This implies that

$x = \pm4 \sqrt{5}$

$x = - 4 \sqrt{5} \: or \: x = 4 \sqrt{5}$

Distribute
4x+4(less than) -6

Subtract 4 on both side
4x(less than) -10

divide 4 both sides
x(less than)-2.5

(Final answer is bold) Good luck
