Question

If p(x) = 3x2-7x +5 , then p(2) = __________

Answer 1

Answer:

Given,

p(x)=3x2-7x+5

Now, we get p(2) by substituting 2 in place of x

Then,

p(2=3(2)2-7(2)+5

=12-14+5

=-2+5

=3

Answer 2

$\textbf{p(2)=3}$

Question :

$\text{if} \: \:\text{ p(x) }= 3 {x}^{2} - 7x + 5$$\text{then \: find p(2)}$

Solution :

$p(x)=3^2-7x+5$

$\text{Now Substitute 2 in place of x}$

$\implies 3((2)^2)-7(2)+5$

$\implies3(4)-14+5$

$\implies12-14+5$

$\implies-2+5$

$\implies3$
