Question

What number is to be added to x^2–2x+1/4 to make it a perfect square

STEP BY STEP EXPLANATION NEEDED !!!!!​

Answer 1

Answer:

3/4

Step-by-step explanation:

y=x^2–2x+1/4

adding 3/4 both sides

y+3/4=x^2-2*x(1)+1/4+3/4

y+3/4=x^2-2*x(1)+1

y+3/4=x-1)^2

hence 3/4 to be added ito make it perfect square

Answer 2

Answer:

3/4

Step-by-step explanation:

the format of a quadratic equation is

ax^2 + bx + c = 0

here to make the equation perfect square we have to make the value of c ,1

suppose if t is added to c then it will be 1 hence,

c + t = 1

● 1/4 + t = 1

● t = 1 - 1/4

= (4 - 1) / 4

= 3/4
