Question

express a^3+b^3in tearms other coefficient of equetio x^2+px+q=0 where a And d are the roots of the equation. ​

Answer 1

Answer:

The coefficient of x in the quadratic equation x 2+px+q=0 was taken as 17 in place of 13, its roots were found to be -2 and -15.

Here, Products of the roots = q=2×15=30, correct value of p=13

Then, quadratic equation becomes,

x 2+13x+30=0

=>(x+10)(x+3)=0

=>x=−10,−3
