sqrt(a-1)=3-a

Solution

a - 1 = 3 - a

Solution

a = 2

Solution steps

a - 1 = 3 - a

Square both sides:

a - 1 = 9 - 6 a + a^{2}

a - 1 = 9 - 6 a + a^{2}

Solve

a - 1 = 9 - 6 a + a^{2} : a = 5, a = 2

a = 5, a = 2

Verify Solutions:

a = 5

False

, a = 2

True

The solution is

a = 2

3/(2*sqrt(x))=0.6

\frac{3}{2 \cdot x} = 0.6

sqrt(3x+1)-sqrt(17-x)=2

3 x + 1 - 17 - x = 2

(3x+1)^{3/2}+2=66

(3 x + 1)^{\frac{3}{2}} + 2 = 66
