sqrt(7x+57)=2x+6

Solution

7 x + 57 = 2 x + 6

Solution

x = 1

Solution steps

7 x + 57 = 2 x + 6

Square both sides:

7 x + 57 = 4 x^{2} + 24 x + 36

7 x + 57 = 4 x^{2} + 24 x + 36

Solve

7 x + 57 = 4 x^{2} + 24 x + 36 : x = 1, x = - \frac{21}{4}

x = 1, x = - \frac{21}{4}

Verify Solutions:

x = 1

True

, x = - \frac{21}{4}

False

The solution is

x = 1

4 x^{2} - 4 x + 1 + (x + 4) = a + 7

7 x + 8 = x + 2

x - 5 + 1 = x

sqrt(7)x-sqrt(5)=sqrt(3x)

7 x - 5 = 3 x

sqrt(10x^2+16x)=5x+8

10 x^{2} + 16 x = 5 x + 8
