whats the question your asking
identify the x-intercepts in the graph y = 3x2 + 19x – 40..sorry connection was slow
The Def'n of the x-intercept is the points where the y-value is zero. So set y to 0 and solve for x

Other answers:

use the quadratic formula
quadratic formula: \[x = \frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]
Quadratic formula for 0 = ax^2 + bx + c\[x= {-b \pm \sqrt{b^2-4ac} \over 2a}\]
thank you guys.. but how do I do that?
are you studying algebra 1 or 2?
2
|dw:1357172313426:dw|just sub into formula and use order of operation to evaluate it
This can also be factored if you are well versed at factoring
you could also, find the roots by looking at the graph of the function
thankyou precal. (:
\[0=3x^2 + 19x – 40\]\[0=(3x-5)(x+8)\]
you have many choices for finding the solution, if you plan to study math beyond algebra 2 learn to factor (but not everything can be factored), learn to use the quadratic formula (works 100% of the time)
im horrible in math, so after alg 2 i will be done with it :P
everything in math (no matter the power) gets written to the 1st power or the 2nd power, so learn to solve those
what will you do in the future? future goals?

im going to own a buisness but i already everything i would need too know. its not going to be huge or complex..just a simple small town business

well math teaches us to be patient and to pay attention to details
in business, you will care about maximizing your profit and minimizing your cost all big businesses started small and grew higher math helps you expand your business watch shark tank, pay attention to when they talk about numbers many people do not get funding because they do not know their numbers some good ideas were passed up by the sharks some bad ideas were given money because the people knew their numbers good luck don't give up on math yet
im givin different answers on this question. im confused which one is wrong or right?
Solutions are the same x=-8 and x=5/3 I just showed that if you use the quadratic formula or factoring, you will get the same solutions.
I wont give up on math, i mean as I have to use it ill start to learn it..in real life situations i guess. and ooohhkk. thankyou (:
