sqrt(5x^2+20x+16)-3=1

5 x^{2} + 20 x + 16 - 3 = 1

x = 0, x = - 4

Solution steps

5 x^{2} + 20 x + 16 - 3 = 1

Move

3

to the right side

5 x^{2} + 20 x + 16 = 4

Square both sides:

5 x^{2} + 20 x + 16 = 16

5 x^{2} + 20 x + 16 = 16

Solve

5 x^{2} + 20 x + 16 = 16 : x = 0, x = - 4

x = 0, x = - 4

Verify Solutions:

x = 0

True

, x = - 4

True

The solutions are

x = 0, x = - 4

(6 x + 9)^{0.5} + 3 = x

25.9 = 2 (9.8) h

2 = 2 x - x^{2}

70 = 4 (30 - q)
