SOLUTION: Find the coordinates of the vertex and the intercepts of f(x)=5x^2+17x-12. When necessary, approximate x- intercepts to the nearest tenth.
I'll show what I got so far:
a=5, b

Question 737529: Find the coordinates of the vertex and the intercepts of f(x)=5x^2+17x-12. When necessary, approximate x- intercepts to the nearest tenth.
I'll show what I got so far:
a=5, b=17
x=-b/2a
x=-17/10 x=-1.7
f(-1.7)=5(-1.7)^2+17(-1.7)-12
f(-1.7)=14.45 -28.9 -12
f(-1.7)=-26.45
vertex=(-1.7,-26.5)
Applying the quadratic formula I get the following:
x=(-17+-23)/10
(-4,0)(3/5,0)
Was that correct?
