Question

verify that 1and 2 are the zero of the polynomial p(x)=xsquare -3x+2

Answer 1

Answer:

1 and 2 are zeroes of p(x)

Step-by-step explanation:

Given p(x) = x²-3x+2

i) if x = 1 , then

p(1) = 1²- 3×1 + 2

= 1-3+2

= 3-3

= 0

p(1)=0

Therefore,

1 is zero of p(x)

ii) If x = 2 , then

p(2) = 2²-3×2+2

= 4-6+2

= 6-6

= 0

p(2) = 0

2 is a zero of p(x)
