Question

help.. I hate fractions!

Answer 1

so far I have x^2-7/9x+1/2x

Answer 2

Given 1st root=-1/2 and 2nd root=7/9
so sum of roots,(-b/a)=(-1/2)+7/9=1/3
product of roots,(c/a)=(-1/2)*7/9=-7/18

SO the quadratic equation is
x^2+(-b/a)x+(c/a)=0
or,x^2+(1/3)x+(-7/18)=0
or,18x^2+6x-7=0

Answer 3

it said that is wrong.

Answer 4

x^2-0.27x-0.385=0

Answer 5

So those fractions are you're answer. You would work backward to find the equation
(x+1/2)(x-7/18)=0
Because solving
x+1/2=0. x-7/9=0
x=-1/2. x=7/9

So foil (x+1/2)(x-7/9)=0
You'll get
x^2 -5/18x -7/18=0
Because it wants you in standard form, all integers should be whole numbers, not fractions so multiply both sides by 18
So your equation in standard form is

18x^2 -5x -7=0
