Find the root of this euation x^2+2-3x

Let's write like this : x^2-3x+2

D=b^2-4ac so...

D=3^2-4*1*2=9-8=1

x=3+1/2=2

x=3-1/2=1

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
