Question

Find the zeros of the quadratic polynomial ݔ

ଶ + 3ݔ − 10 and verify the relationship

between its zeros and coefficients​

Answer 1

Answer:

let factorise by splitting the mid term method

x2+3x-10=0

x2+5x-2x-10=0

x(x+5)-2(x+5)

(x-2)(x+5)

x=2,-5

to verify--

sum of zeroes =-b/a=-3/1=-3

alpha+beta=2-5=-3

product of zeroes=c/a=-10

alpha beta=2×-5=-10

hence verified
