Question

Help me explain why the discriminant of this quadratic equation is 0. NO SPAM PLS I will mark you brainliest! :)
The quadratic equation is 0=x^2-2x+ 1
My textbook wrote that the discriminant is 0. Why?
The formula to find the discriminant is b^2-4ac. So in this equation, a=1, b=-2 and c=1.
I thought the discriminant is 4. Please explain well I will mark you brainliest!

Answer 1

Answer:

HERE IS REQUIRED ANSWER

Step-by-step explanation:

DISCRIMINANT=b²-4ac

Here,a=1,b= -2 ,c=1

Substitute in above formula,

=(-2)²-4×(1)×(1)

=4-4

=0

Then roots are equal.

PLEASE PLEASE PLEASE.

Answer 2

Answer:

0

Step-by-step explanation:

dear, discriminant is......

D= b^2-4ac

here a=1, b= -2 and c= 1

now,

according to the formula

D=

(-2)^2 - 4(1)(1)

=(-2)(-2) - 4.

= 4 - 4. { because - (-)= +}

= 0
