A) \[{{x}^{2}}-3\sqrt{7}x-70\]
B) \[{{x}^{2}}+3\sqrt{7}x+70\]
C) \[{{x}^{2}}+3\sqrt{7}x-70\]
D) \[{{x}^{2}}-3\sqrt{7}x+70\]
Correct Answer: C
Solution :
Sum of zeroes \[=2\sqrt{7}+\left( -5\sqrt{7} \right)=-3\sqrt{7}\] |
Product of zeroes \[=2\sqrt{7}\times \left( -5\sqrt{7} \right)=-70\] |
The quadratic polynomial are |
\[{{x}^{2}}-\](sum of zeroes) x + product of zeroes |
\[{{x}^{2}}-\left( -3\sqrt{7} \right)x-70\] |
\[={{x}^{2}}+3\sqrt{7}x-70\] |
