1.	A quadratic polynomial,whose zeroes are -3 and 4 is
Answer» Answer: We KNOW that the SUM of the ZEROES of the polynomial is -b/a. Also product of the zeroes of the polynomial is c/a. So, Sum of zeroes, (-3)+4=1 So -b/a=1 so b=-1 and a=1 Product of zeroes, (-3)(4)=(-12) So c/a=(-12) so c=(-12) and a=1 So the quadratic polynomial is, x^2-x-12*

Answer»

Answer:

We KNOW that the SUM of the ZEROES of the polynomial is -b/a.

Also product of the zeroes of the polynomial is c/a.

So,

Sum of zeroes, (-3)+4=1

So -b/a=1

so b=-1 and a=1

Product of zeroes, (-3)*(4)=(-12)

So c/a=(-12)

so c=(-12) and a=1

So the quadratic polynomial is,

x^2-x-12
