Question

Please solve the equation
√(5a+2)=-√(a+7)

Answer 1

I got -3/2, please check my answer

Answer 2

try squaring both sides

5a +2 = a +7

4a = 5
a = 5/4

Answer 3

if you sub these two results into the original equation it won't be satisfied so there is NO solution. I f you draw two graphs of each side you will see they don't intersect

Answer 4

the RHS is negative for all values of x. LHS cannot have negative values
