Question

Find the value of "P" Form the polynomial x2+3x+P if one of the zeroes of the polynomial is 2

Answer 1

Answer:

-10

I will tell you how it came.

Step-by-step explanation:

${x}^{2} + 3x + p = 0$

Here one of the zero is 2

Substitute 2 in the given equation

${2}^{2} + 3(2) + p = 0 \\ 4 + 6 + p = 0 \\ 10 + p = 0 \\ p = 0 - 10 \\ p = - 10$

Answer 2

Answer:

-10

Step-by-step explanation:

since -(a+b) = 3

so a is given 2

that implies b is -5

and p= ab = -10
