Question

To find the zeroes of the quadratic
polynomial by using graph paper
(i) p(x)=x2-3x+2
(ii)p(x )=x2-4x+4
(iii)p(x) =x2 -4x +5​

Answer 1

Answer:

For #1

let,x-1 be the factor of p(x)

so,x-1=0

x=1

by putting the value of x we get

• x²-3x+2=0

(1)²-3×1+2=0

1-3+2=0

3-3=0

For#2

let,x-2 be the factor of p(x)

x-2=0

x=2

by putting the value of x we get

• x²-4x+4=0

(2)²-4×2+4=0

4-8+4=0

8-8=0

For #3
