Question

Solve for x::no. 29​

Answer 1

Answer:

x = 1/4

Step-by-step explanation:

√x  + 2x =1

√x  = 1 - 2x

squaring on both sides

x = 1 + 4x²- 4x

4x² - 5x + 1 = 0

by solving the equation we get the value of x to be 1 or 1/4

x = 1 or 1/4

when we substitute 1 in the equation the answer is coming different

so the only value of x satisfying this equation is 1/4

Answer 2

Answer:

√x+2x=1

√x=1-2x

(√x)²=(1-2x)². (Squaring both side)

x=1+4x²-4x

4x²-5x+1=0

Middle term splitting method

4x²-4x-x+1=0

4x(x-1) -1(x-1)=0

(4x-1)(x-1)=0

Now

x=1/4

x=1
