Question

Value of P if the expression 3a²+ 2a – P equals to 3 for a = 2
​

Answer 1

Answer:

13

Step-by-step explanation:

3a² + 2a - p = 3

⇒ 3 x 2² + 2 x 2 - p = 3

⇒ 12 + 4 - p = 3

⇒ 16 - p = 3

⇒ -p = 3 - 16 = -13

⇒  p = - (-13) = 13

Answer 2

As per the details provided in the question.

In the above question, we have the details as follow.

The given data is the equation that is 3a²+ 2a – P=3

Where value of a=2

We have to find the value of P.

Here we have to simplify the given equation and substitute the value of a in the given equation we get.

Thus, simplifying the given equation we get,

$3a^{2}+2a-P=3$

Substitute the value of a=2 in above expression we get,

$3\times(2)^{2}+2\times(2)-P=3 \\(3\times 4)+(4)-P=3\\12+4-P=3\\16-P=3$

Taking constant term one side we get,

$-P=3-16\\-P=-13$

Multiply negative side both side we get,

P=13

Hence the value of P in the given equation is 13.

Note:-Value of P if the expression 3a²+ 2a – P=3 for a = 2
