For what values of m does the graph of y = 3x2 + 7x + m have two x-intercepts

Irina18 [472]

we are given

$y=3x^2+7x+m$

To find x-intercept means we have to find zeros

and for finding zeros , we will use quadratic formula

and we have it has two x-intercepts

so, it's discriminant must be greater than 0

so, we will find discriminant

$D=\sqrt{b^2-4ac}$

now, we can compare with

$y=ax^2+bx+c$

$y=3x^2+7x+m$

and then we can find a , b and c

$a=3,b=7,c=m$

now, we can find D

$D=\sqrt{7^2-4*3*m}$

$D=\sqrt{49-12m}$

It has two x-intercepts

so,

$D=\sqrt{49-12m}>0$

now, we can solve for m

$49-12m>0$

$12m$

$m$ ............Answer
