sqrt(7x+56)=x+8

7 x + 56 = x + 8

x = - 1, x = - 8

Solution steps

7 x + 56 = x + 8

Square both sides:

7 x + 56 = x^{2} + 16 x + 64

7 x + 56 = x^{2} + 16 x + 64

Solve

7 x + 56 = x^{2} + 16 x + 64 : x = - 1, x = - 8

x = - 1, x = - 8

Verify Solutions:

x = - 1

True

, x = - 8

True

The solutions are

x = - 1, x = - 8

8 x - 20 = x - 1

44 - 5 x = x - 6

- 5 - 7 x + 4 + x = 7 - 6 x

8 x + 17 = x + 3

b, x = \frac{- b + b ^{2} - 4 a c}{2 a}
