I don’t understand the question, can you restate it?
Step 1: find two numbers that multiply to give ac ( in other words a x c ) and add to give b
step 2: rewrite the middle with those numbers
step 3: factor the first two and last two terms separately
step 4: if you’ve done this correctly, your two new terms should have a clearly visible common factor
and then you’re done! hope this helps!
4^3*4^4 / 4^6 = 4^7 / 4^9 = 1/4^2
answer is C. 1 / 4^2
Answer:
<h3>Step 4</h3>
Step-by-step explanation:
Given the expression 7+(-2)
Let 7 be 7 positive tiles since it is a positive number
Let -2 be 2 negative tiles being a negative number
7+(-2) = 7 positive tiles <em>and</em> 2 negative tiles
note that + * - will give minus sigh (-), the expression will become:
7+(-2) = 7-2
7-2 = 5
Hence the expression gives 5 positive tiles not 2 positive tiles according to Jillian calculations in step 4.
Hence Jillian made an error in step 4
