Question

Q5. Find the quadratic polynomial whose sum and product of the zeroes are -2√ and -9

respectively. Find the zeroes of that polynomial by factorization.​

Answer 1

Answer:

${x}^{2} + 2x - 9$

Step-by-step explanation:

let roots are A and B

A + B = -2

AB = -9

EQUATION having roots A and B is

${x}^{2} - (a + b)x + ab$

${x}^{2} - ( - 2)x \: + ( - 9)$

${x}^{2} + 2x - 9$

Answer 2

Step-by-step explanation:

the formula to find quadratic polynomial is x^2-(sum of zeros)x+product of zeroes
