What are the x-intercepts of the graph of the equation y = x² + 4x -5 ?
-5 and 1
5 and 1
5 and -1
-5 and 0

-5 and 1

Step-by-step explanation:

x-intercept means where a certain equation touches the x-axis. At this point the value of y will be 0.

So, put y = 0 in y = x² + 4x -5

0 = x² + 5x - x - 5

0 = x(x + 5) - 1(x + 5)

0 = (x - 1) (x + 5)

Either,

x - 1 = 0

x = 1

Or,

x + 5 = 0

x = -5

14

step-by-step explanation:

14 x 3 = 42
