Question

Find the zeroes of the quadratic polynomial √2

2 + 7 + 5√2.

Pls answer exam time​

Answer 1

Step-by-step explanation:

the zeroes of the quadratic polynomial be α=3+

7

,β=3−

7

Then, a+β=3+

7

+3−

7

=6

αβ=(3+

(

7))×(3−

7

)=9−7=2

Sum of zeroes =α+β=6Product of zeroes =αβ=2

Then, the quadratic polynomial =x

2

−( sum of zeroes )x+ product of zeroes =x

2

−(6)x+2

=x

2

−6x+2
