sqrt(9x+145)=2x+20

9 x + 145 = 2 x + 20

x = - 5

Solution steps

9 x + 145 = 2 x + 20

Square both sides:

9 x + 145 = 4 x^{2} + 80 x + 400

9 x + 145 = 4 x^{2} + 80 x + 400

Solve

9 x + 145 = 4 x^{2} + 80 x + 400 : x = - 5, x = - \frac{51}{4}

x = - 5, x = - \frac{51}{4}

Verify Solutions:

x = - 5

True

, x = - \frac{51}{4}

False

The solution is

x = - 5

a + 5 = a + 44

x - 5 + 2 x - 9 = 2 + 4 x - 36

θ, r = 1 - 2 θ

x + 3 - 2 = x

x^{0.7} = x^{0.3}
