find the zeros of the following quadratic polynomial and verify the relationship between zeros and the coefficients x²-5x
Answers
Step-by-step explanation:
x²-5x =0
=>x(x-5)=0
=>x=0 and x=5
Hence the zeroes are 0 and 5.
Therefore, a=1 , b= -5 , c=0
Verification:-
•Sum of the zeroes= -b/a
=-(-5)/1
= 5
•Product of zeroes = c/a
= 0/1
=0
Hence proved.
And that's all your answer
Answer:
zeroes are 2 and 3
Step-by-step explanation:
let the zeroes of the polynomial= alpha and beta.
p(x)=x²-5x= x²-5x+6
ax²+bx+c
a=1,b=-5,c=6
by splitting middle term
= x²-2x-3x+6
= x(x-2) -3(x-2)
= (x-2)(x-3)
x-2=0
x=2= alpha
x-3=0
x=3=beta.
verification
sum of zeroes= alpha+beta =2+3= 5
sum of zeroes= alpha+beta= -b/a = -(-5)/1= 5
product of zeroes = alpha x beta = 2*3=6
product of zeroes = alpha x beta = c/a = 6/1 = 6
hence verified.
