Question 50:
Given the equation x2+px−10=0.
The question implies that the roots are given in the options, and we need to find p. Assuming the roots are 2 and −5 (as their product is −10, matching the constant term), we can find p.
For a quadratic equation ax2+bx+c=0, the sum of the roots is −ab.
In this equation, a=1, b=p, c=−10.
Sum of roots =2+(−5)=−3.
From the formula, sum of roots $=
