X^2-4x-5=0
according viet’s theorem
the roots are 5 and -1
Remember that if something is raised to a fraction exponent, the denominator of the fraction is the radical and the numerator stays a power. So it becomes:

Hope this helps
Equal to a+b on the algebra
Area = 1/2 * base * height
6 = 1/2 * base * 3
lengths of the base = 6 / (3*1/2) = 6 / 1.5 = 4 inches answer
