Question

What will be a quadratic polynomial whose zeroes are -3 and 4

Answer 1

Given :-

Zeroes of the Quadratic polynomial :-

-3 , 4

let -3 be alpha , 4 be beta .

so we know that

alpha + beta = -b /a

= -3 + 4

= 1

•°• b = -1 and a = 1

alpha × beta = c /a

-3 × 4 = -12

•°• c = -12 , a =1

A quardratic polynomial will be In tell form of ax^2 + bx + c = 0

Substitute the values we got In the above equation

x^2 -x -12

Answer :- x^2 -x -12.
