what is sqrt(7x-5)=-2sqrt(x-2)
whaat does it equal or what is x??
sqrt (7x - 5) = -2(sqrt (x - 2) square both sides
7x - 5 = (4) (x - 2) simplify
7x - 5 = 4x - 8
7x - 4x = - 8 + 5
3x = -3
x = -1
However......tis makes both expressions under the roots negative......and the value of a negative square root is not real....so....
No real solutions
