sqrt(x-7)=x-7

Solution

x - 7 = x - 7

Solution

x = 8, x = 7

Solution steps

x - 7 = x - 7

Square both sides:

x - 7 = x^{2} - 14 x + 49

x - 7 = x^{2} - 14 x + 49

Solve

x - 7 = x^{2} - 14 x + 49 : x = 8, x = 7

x = 8, x = 7

Verify Solutions:

x = 8

True

, x = 7

True

The solutions are

x = 8, x = 7

Popular Examples

x + 1 + 5 = x

x + 9 - 4 = 1

x+2-2sqrt(x+3)=0

x + 2 - 2 x + 3 = 0

sqrt(4y+16)-sqrt(y-5)=6

4 y + 16 - y - 5 = 6

256=2(10j-6)^{7/6}

256 = 2 (10 j - 6)^{\frac{7}{6}}
