Question

Solve this equation. square root of x plus square of x minus 20 equals 10 I hope you understand thisThnx ?

Answer 1

sqrt(x) + (x-20)^2 = 10

by trial

sqrt(25) + (25-20)^2 = 10

x=25

Answer 2

Square everything to get rid of square root symbles.

That equals = (x) + (x - 20) = 100

Simplify

2x - 20 = 100

Add 20

2x = 120

Divide by 2

x = 60
