Question

What are the x-intercept(s) of the graph of the equation y − x^2 = −4x − 5?

(1, 0) and (−5, 0)

(1, 5)

(−1, 0) and (−5, 0)

(−1, 0) and (5, 0)

Answer 1

Okay, first you want to put everything on one side to make the equation equal 0

Answer 2

You should get an equation like this ax^2+bx+c=0

Answer 3

okay then what

Answer 4

Or rather in this one the equation would equal y which is the same as f(x)..

Answer 5

Anyways, you would then do the quadratic equation

Answer 6

Do you know what that is?

Answer 7

no i am so confussed but i choose the answer (-1,0) and (5, 0)

Answer 8

i have no clue

Answer 9

OK. The quadratic formula is
