Question

Where does the graph of y = 3x2 − 10x − 8 cross the x-axis?

Answer 1

it's no graph

Answer 2

On simplifying the equation , y = -10x-2 ,When the line crosses the x-axis, the y co-ordinate of the point must be zero.So putting y=0 in the above equation, x= -1/5. So the line crosses the x axis at ( 0 , -1/5 )

Answer 3

thanks
