Question

medal rewarded please help!!
Two sets of quadratic equations are shown below in various forms.
Line 1: x2 + 3x + 2 (x + 1)(x + 2) (x + 1.5)2 − 0.25
Line 2: x2 + 5x + 6 (x + 2)(x + 3) (x + 2.5)2 + 6.25
Which line contains three equivalent expressions?
Line 1 only
Line 2 only
Both Line 1 and Line 2
Neither Line 1 nor Line 2

Answer 1

I don't get it, do they want the expressions to be equivalent to the other line?

Answer 2

I honestly have no idea

Answer 3

@wio please help

Answer 4

Okay, you have to simplify the others expressions to see if they are equivalent.

Answer 5

\[
(x + 1)(x + 2)=x^2+3x+2
\]So it is equivalent to \(x^2 + 3x + 2\)

Answer 6

I don't get it... I've been staring at this question for an hour...

Answer 7

Ooohhh I get it now

Answer 8

would it be C? @wio

Answer 9

Ya got it!!!!
