How do you complete the square to rewrite y= x^ -6x + 15 in vertex form

Vaselesa [24]

Vertex form of a quadratic equation is $y=a(x-h)^{2}+k$
where (h, k) is the vertex.

Our aim is to write the expression $y=x^{2} -6x+15$ in the form
$y=a(x-h)^{2}+k$

$y=x^{2} -6x+15$

$y=x^{2} -2*3*x+15$

$y=(x^{2} -2*3*x+ 3^{2})-3^{2}+ 15$

$y=(x-3)^{2}-9+15$

$y=(x-3)^{2}+6$

What is -1.1 repeating as a fraction

Thepotemich [5.8K]

$Hey \\ There!$

$\frac{-1.1}{1} ( \frac{10}{10} )\\ \\ -1.1(10) = -11 \\ \\ 1(10)= 10 \\ \\ \\ Fraction: \frac{-11}{10}$ this is also $equal$ to: $-1\frac{1}{10}$

Your answer would probably be: $\frac{-11}{10} = -1\frac{1}{10}$

Good luck on your assignment and enjoy your day!
