Question

find a quadratic polynomial whose zeroes are 3 and -7/5​

Answer 1

Find the quadratic polynomial whose zeroes are 3 and-5

Answer : x² + 2x - 15.

Step by step explanation : Let one zero (3) be α ...

Sum of zeros = α + β = ( 3 + { - 5 } ) = - 2.

Product of zeros = αβ = { 3 x - 5 } = - 15. We know that,

p(x) = x² - ( α + β )x + αβ p(x) = x² - ( - 2 )x + ( - 15 ) ...

The quadratic polynomial whose zeroes are 3 and -5 is x² + 2x - 15.
