Question

Two sets of equatic expressions 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?

Answer 1

For greater clarity, please express exponentiation using the ' ^ ' symbol.

Right: x^2 (x squared)
Wrong: x2 (Looks like 2x)

Answer 2

Hints: Factor x2 + 3x + 2. Factor x2 + 5x + 6. simplify \[(x + 1.5)^2 − 0.25\] ...

Answer 3

and simplify (expand) \[ (x + 2.5)^2 + 6.25\]

Answer 4

this is the question

Answer 5

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 6

i think it is line 1 only
