Question

BRAINLIEST. No spam -_-

Answer 1

Answer:

$m$

Step-by-step explanation:

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

$49-12m>0\\12m$
