Complete the square f(x) = x^2 + 4x - 8 <br><br><br> PLZ help me ;c
Semenov [28]
Ok, first group x terms
f(x)=(x²+4x)-8
factor out quadratic coefient (no need but that's the step)
f(x)=1(x²+4x)-8
take 1/2 of the linear coefient and square it
4/2=2, (2)²=4
add positive and negative of it insides the parenthasees
f(x)=1(x²+4x+4-4)-8
factor perfect square
f(x)=1((x+2)²-4)-8
distribute
f(x)=1(x+2)²-4-8
f(x)=1(x+2)²-12
and, now if we wanted to find the x intercepts where f(x)=0 then
0=1(x+2)²-12
12=(x+2)²
+/-2√3=x+2
-2+/-2√3=x

x=-2+2√3 or -2-2√3
that is where the x intercept are

and completed square form is
f(x)=(x+2)²-12

Which could be the area of a face of the rectangular prism? A rectangular prism with a length of 3 meters, width of 4 meters, an
blagie [28]

Answer:

6m²

Step-by-step explanation:

Because the question asks for the area of a face but it doesn't indicate which face then it can be any of the faces.

2m x 3m = 6m²

2m x 4m = 8m²

3m x 4m = 12m²

In your case one of the possible answers is 6m² - so that is the one they are looking for.
