#

it should be 1

#

but

#

they both intersect

#

2 distinct points

#

you were right about that

#

hmm

#

-3/10?

#

ok

#

np

#

i can see that

#

wow

#

oh i see

#

you need to have similar fractions

#

wait for a moment

#

so that they can have the same denomenator

#

but

#

its safer to do it this way

#

yh

#

np

#

also

#

if you were to factorise the expression -3/10 x +2.7x -6

#

you will get x=5 and x=4

#

which is similar to -x^2+9x-20

#

yes

#

you can also find the intersection

#

if you want

#

disriminant would save you enouph time
