Answer:
B
Step-by-step explanation:
The value of the polynomial for x = 3 is the value of P(3)
P(3) = 2(3)³ - 7(3)² + 7(3) - 12 = 54 - 63 + 21 - 12 = 0 → B
Answer:
i d k lol im just tryna get points
Step-by-step explanation:
have a cookie and good luck tho
First simplify
(x^2+2x+1)-4
x^2+2x-3
Then factor
(x+3)(x-1)=x^2+2x-3
I solved your other quesiton too.
Answer:
Yes
Step-by-step explanation:
15 = 3(5)
15 = 15
You plug in the point
Complete the square:
<em>x</em> ^2 - 2<em>x</em> + <em>y</em> ^2 + 4<em>y</em> + 1 = 0
(<em>x</em> - 1)^2 + (<em>y</em> + 2)^2 + 1 = 1 + 4
(<em>x</em> - 1)^2 + (<em>y</em> + 2)^2 = 4 = 2^2
Hence the center is (1, -2) and the radius is 2. (D)
