Answer 2

SOLUTION:-

Given:

x² -px + 9 =0

To find:

Find the value of p.

Therefore,

The roots of the quadratic equation;

Ax² + Bx + C= 0 as compared to.

⚫A= 1

⚫B=-p

⚫C=9

Discriminate,(D)= b² -4ac=0

So,

=) (-p)² - 4(1)(9)=0

=) (-p)² - 36 =0

=) (-p)² = 36

=) (-p)² = (6)²

=) -p= 6

=) p= -6
