Question

when x= 3,then find the value of p(x)=4x²+x+3​

Answer 1

Answer:

$p(x) = 4 {x}^{2} + x + 3 \\ p(3) = 4( {3}^{2} ) + 3 + 3 \\ = 4(9) + 3 + 3 \\ = 36 + 6 \\ = 42$

Answer 2

Answer:

p=14

Step-by-step explanation:

1. Find the question given.

$x=3\\p(x)=4x^{2} +x+3$

2. Turn all *$x$* into 3. ($x=3$)

$p(3)=4(3^{2}) +3+3$

3. You will get $4(3^{2})=4(3$ x $3=9)$. Thus, $4(9)=$ $4$ x $9$ $= 36$. Next, plus the numbers.

  $3p=36+6\\3p=42$

4. You will get $3p=42$ when you total the numbers. Thus, *$3$* from *$3$$p$* will be brought over resulting in divide/fraction.

   $p=\frac{42}{3} \\p=14$

That's all! Hope it is understandable and helps you
