Question

Find the quadratic polynomial whose zeroes are 2+ root 7 and 2- root 7 .

Answer 1

it will come zero because if tow number in different sing so it is zero

Answer 2

Answer:

α = 2√7 , β = -2√7

sum of zeros (α+β)= 2√7 + (-2√7)

                             = 2√7 - 2√7

                             = 0

product of zeros (αβ) = (2√7)(-2√7)

                                  = -4×7

                                  = -28

quadratic polynomial = [x²+(sum of zeros)x+product of zeros]

                                  = [x²+ 0x + (-28)]

                                  = x² + 0x - 28

                                  or x² - 28
