√x+10 = 2

√4x+1 = 2x-1

√36x²-12x+1 + 3x = 4

√x+10 = 2

x+10=4

x=4-10

x=-6

√4x+1 = 2x-1

4x+1=4x^2-4x+1

4x^2-4x+1-4x-1=0

4x^2-8x=0

4x (x-2) = 0

4x=0

x=0

x-2=0

x=2

√36x²-12x+1 + 3x = 4

√36x²-12x+1=4-3x

36x^2-12x+1=16-24x+9x^2

36x^2-12x+1-9x^2+24x-16=0

27x^2+12x-15=0

9x^2+4x-5=0

D=4^2-4*9 * (-5) = 16+180=196=14^2

x1 = ((-4) + 14) / 2*9=10/18

x1=5/9

x2 = ((-4) - 14) / 2*9=-18/18

x2=-1
