Question

For which value of x does the graph of y = 2x2 − 7x + 6 cross the x-axis?

-2/3

-3/2

2

3

Answer 1

for the graph to cross the x-axis,its y co-ordinate must be 0
so just put y=0 in the graph equation
u will get a quadratic in x
solve the quadratic to get x values..

Answer 2

at x axis,y=0 so,
put y=0
0=2x2-7x+6
solving quadratic
2x2-4x-3x+6
2x(x-2)-3(x-2)=0
(2x-3)(x-2)=0
x=3/2,2
