Question

a quadratic polynomial whise zeros are 7 and 5 is​

Answer 1

Answer:

Solution:-

As the zeroes are given, i.e., 7 and -5.

∴ Sum of roots =7+(−5)=7−5=2

Product of roots =7×(−5)=−35

As we know that, a quadratic polynomial whose xeroes are given can be represented as-

x 2

−(sum of roots)x+product of roots=0

⇒x

2 −(2)x+(−35)=0

⇒x

2 −2x−35=0

Hence, the polynomial is x 2 −2x−35=0.
