Question

13.Find the value of “p” from the polynomial x2 + 3x + p, if one of the zeroes of the polynomial is 2.​

Answer 1

Answer:

x^2+3x+p=0

zero = 2

so put 2 in place of x

(2)^2+3(2)+p= 0

4+6+p= 0

10 +p=0

p= -10ans

hope it will help you please mark me brainlist thankyou

Answer 2

Answer:

As zero of polynomial is 2

So putting 2

\begin{gathered} {2}^{2} + 3 \times 2 + p = 0 \\ 4 + 6 + p = 0 \\ p = - 10 \: ans\end{gathered}

2

2

+3×2+p=0

4+6+p=0

p=−10ans
