Question

3. If a and b are the zeroes of a polynomial px square- 5x+q, then the values of p and
a + b = ab = 10, are
​

Answer 1

Answer:

hey mate ... here is ur answer ....

values of p and q are 12 and 5 respectively .

Step-by-step explanation:

We know that, for a quadratic equation ax2+bx+c=0,Sum of roots = α+βand product of roots = αβwhere α and β are the roots of theequation.

Also, α+β=−ba and αβ=ca

So,  a+b=5p and ab=qp.

It is given that a + b = ab = 10

⇒ 10=5p

Hence, p = 12

Also, ab=qp

⇒10=qp

⇒q=10p

⇒q=10× 12

⇒q=5

hope this will help uh ...

have a great day ahead ...
