Question

Two sets of quadratic expressions are shown below in various forms:

Line 1: x2 − x − 6 (x + 2)(x − 3) (x + 0.5)2 − 6.25
Line 2: x2 − x − 2 (x + 1)(x − 2) (x − 0.5)2 − 2.25

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

@Nurali

Answer 2

umm

Answer 3

do this
simplify x^2-x-6
and x^2-x-2

Answer 4

in () form

Answer 5

you will get (x+2)(x-3) for first
and for 2nd (x + 1)(x − 2)

Answer 6

so atleast till this point they are equivalent

Answer 7

yea :D

Answer 8

well
now we have to see for 3rd

Answer 9

now put some value for x
suppose x=2

Answer 10

when you solve (x+2)(x-3) =-4
and (x + 1)(x − 2) = 0

Answer 11

hey is that squared it last equation

Answer 12

i think so im not quit sure

Answer 13

so for x=2
we get
(x + 0.5)2 − 6.25 = 0

and

(x − 0.5)2 − 2.25 = 4

Answer 14

the values are not equal

Answer 15

so neither of them have equivalent expression

Answer 16

ok thank you so much :3

Answer 17

welcome

Answer 18

did u get this right?
