Question

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



-3/2

-2/3

2

3

Answer 1

equate y to zero

2x^2 - 7x + 6 = 0

now factor

(2x+3)(x+2)

equate the factors to zero

2x + 3 = 0

AND

x + 2 = 0

can you do it from there?

Answer 2

Sorry, no. Can you just tell me the answer?

Answer 3

2x + 3 = 0

isolate x

2x = -3

divide both sides by 2 to get x

i am not going to give you the answer..it should be obvious from there on -_-
