Question

P(x) = 4x²-3x+7 at x=1​

Answer 1

Hello!

Answer:

$It\:\:is\:\:P = 8$

Step-by-step explanation:

$P(x) = 4x^2-3x+7$

We replace x = 1:

$P\left(1\right)=4\left(1\right)^2-3\left(1\right)+7$

We delete the parentheses:

$P=4\cdot \:1-3\cdot \:1+7$

We multiply the numbers:

$P=4-3+7$

We add and subtract:

$P=8$
