## anonymous 4 years ago what is the vertex form for:y= 1/3x^2+2x+3 ?

1. anonymous

you complete the square inside the parentheses of $\frac{1}{3}\bigg(x^2+6x + 9 \bigg)$ then multiply through with the 1/3

Again, like much of math, when in doubt factor and see if it helps. This is pretty easy after factoring the 1/3 out.
