Question

What are the x-intercept(s) of the graph of the equation y − x2 = −4x − 5?

Answer 1

Answer choices?

Answer 2

(1, 0) and (−5, 0)

(1, 5)

(−1, 0) and (−5, 0)

(−1, 0) and (5, 0)

Answer 3

Okay well, To find the x intercepts, set y = 0, and solve.

BTW, answer B cannot be correct because it doesn't have y = 0

So with y=0 you have ---> x2 - 4x - 5 = 0

This can be expressed as (x+1)*(x-5) = 0

This can be solved separately as x+1 = 0 and x-5 = 0 to find the two answers.

So the answer would be D :)

Answer 4

thanks ill put more up :)

Answer 5

okay
