A) $2log_{b}q + 8 log_{b} t= \\ log_{b} q^{2} + log_{b} t^{8} = \\ log_{b} q^{2} t^{8}$
Answer: B )
b ) $4 log x - 6 log( x + 2 ) = log x^{4} - log ( x+2 )^{6}= \\ log \frac{ x^{4} }{(x+2) ^{6} }$

How do I solve this problem

Alex73 [517]

Find a common denominator between the two (this case it would be 18) and bring the fractions up, so 10/9 would be 20/18, and 3/2 would be 27/18. Then, multiply across, and simplify to lowest terms.

Write in vertex form

nasty-shy [4]

Vertex form: $y=a(x-h)^2+k$

So firstly, put x^2 - 4x into parentheses: $y=(x^2-4x)+6$

Next, we need a perfect square inside the parentheses. Divide the x coefficent by 2 then square that result. In this case, -4 ÷ 2 = -2, (-2)²= 4. Add 4 inside the parentheses and then subtract 4 outside the parentheses:

$y=(x^2-4x+4)+6-4\\y=(x^2-4x+4)+2$

Lastly, factor what's inside the parentheses and <u>your vertex form is $y=(x-2)^2+2$ </u>
