Question

6
Find
quadric polynomial with zeroes (-2) and 1/2​

Answer 1

x²+3/2x-1

Explanation:

As we know Formula of a quadratic polynomial is

x²-(Sum of zeros)x + Product of zeros

Now,

Sum of Zeros = 1/2+(-2) = -3/2

Product of Zeros = 1/2.(-2) = -1

Again, Putting It in formula,

= x²-(-3/2)+(-1)

= x² + 3/2x - 1

Therefore, Our required answer is x² + 3/2x - 1
