Question

Gitu saves 12k daily from her pocket money. At the end of each month, she uses this money to buy some
notebooks and distributes them to 5 orphans. If k represents the difference of the two zeroes of the quadractic
polynomial x2 - 7x + 12, then Find the zeroes of the given polynomial and the value of k.
pls answer I will mark you as the brainiest.. ​

Answer 1

Answer:

a=1,b=7,c=12

Factors of x²+7x+12

=x²+4x+3x+12

=x(x+4)+3(x+4)

=(x+4)(x+3)

Zeroes of the polynomial

x²+7x+12 =0

(x+4)(x+3)=0

x= -4,-3

ZEROES = -4, -3

SUM OF ROOTS = -4-3=-b/a=-7/1

=> -7=-7

PRODUCT OF ROOTS= -4*-3=c/a

=> 12=12
