Question

the quadratic polynomial whose sum and product of zeros are respectively -4and3 (a)x²-x-12(b)x²+x-12(c)x²-4x+3(d)x²+4x+3​

Answer 1

Answer:

x^2 + 4x + 3

i.e, option (D).

Step-by-step explanation:

we know, if sum and product of zeroes of a quadratic polynomial is given…

Then *quadratic polynomial = x^2 - (sum of zeroes)x + (product of zeroes)*

                                             = x^2 - ( -4 )x + ( 3)

                                             = x^2 + 4x + 3

which is the required answer!

Hope it helps you and if any doubt, please do ask…

Answer 2

Answer:

the correct answer is option d.

Step-by-step explanation:

• Because Product of zeros is c÷a=3
• 3÷1=3
• 3=3.

Sum of zeros is- b ÷a=-4

• -4÷1=-4
• - 4 = - 4.
