Question

find the zeros of the quadratic polynomial xsquare + x - 12 and verify the relationship between the zeros and the coefficient​

Answer 1

Answer:

We need to find two such numbers whose sum is 1 and product is -12. Two such numbers are 4 and -3. Either (x + 4) = 0 or (x - 3) = 0. Hence, two zeroes of this polynomial are -4 and 3.

Answer 2

¶¶¶••••Answer••••¶¶¶

Given, x²+7x+12

zeros

x² +7x+12=0

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

x=−3,−4

verification,

sum of roots =− a/b =− 1/7

=−7

product of roots = a/c

= 1 / 12

=12

Hence proved.
