Question

can someone please help me

y=x^2-36
y=x-16

Answer 1

im guessing you want to solve the system?

start by setting the two equations equal to each other

x^2 - 36 = x - 16

know where to go from here?

Answer 2

not really

Answer 3

ok, now re-arrange the variables to get it into quadratic form

x^2 - x - 20 = 0

Answer 4

ok

Answer 5

then factor

Answer 6

so would that be x^2-36x-20=x

Answer 7

or is it x^2-36x-20=0

Answer 8

nope, remember, to factor, we want to find two numbers that add to -1 and multiply to get -20

Answer 9

x^2 - x - 20 = 0

(x-5)(x+4) = 0

so x = 5 and x = -4

now find the matching y values

Answer 10

still there?
