Alright it would be amazing if someone could help me out with this. For the 2 following equations could someone;

a. Find the discriminant
b. Solve by Factoring (Find Zeroes) (First equation only)
c. Solve using quadratic formula
d. Put the equation into vertex form


1. F(x)= 3x^2-5x-2
2. F(x)= 4x^2+7x-5

I JUST FUCKING ANSWERED THIS ON /adv/

Lols i have this in a math exam on monday, fucking a levels

A
>1. F(x)= 3x^2-5x-2
= 6x-5

>2. F(x)= 4x^2=7x-5
Why the equals in the middle?

mfw i realize learning math in anything but english makes you handicapped

also fuck you captcha

Of course it's not right. The OP should do his own fucking homework.

>> No.2307609

get your fucking 7th grade homework off /sci/

you think these problems are fucking hard?
you better hit the books kid

the discriminant is equal to the first differential.

+-sqrt(b^2 - 4ac) = 2ax + b

solve for x

I know how to do it, I just want to make sure its right

>> No.2307684

>>2307633

Ok then, please explain to us all why the differential and the discriminant are equal?

Actually I bet none of you /sci/fags can explain that shit.
