Question

find a quadratic polynomial who's sum and product is -2√3,9​

Answer 1

Answer:

hence required answer is x^2 +2✓3x +9 =0

Step-by-step explanation:

let roots of quadratic equation are p and q

then p+q = -2✓3 and pq=9

now general form of quadratic equation whose roots are p and q is x^2 - (p+q) x +pq = 0

now x^2 -(-2✓3)x + 9 = 0

x^2 +2✓3 x +9 =0 is correct answer
