The following steps of solving for the roots of 2x² - 4x -3 = 0 were retrieved from another source
Step 1 2x² - 4x = 3
Step 2 2(x² - 2x) = 3
Step 3 2(x² - 2x + 1) = 3 + 1
Step 4 2(x - 1)² = 4
From this, we can see that on Step 3, Tran made a mistake of adding 1 to 3. As we can see, 2(x² - 2x + 1) = 2x² - 4x + 2. That means, instead of adding 1, it should have been 2.
Therefore, the step that Tran first made an error is Step 3<span>.</span>

Answer:
150cw + 80w^2
Step-by-step explanation:
so we start with
(15c + 8w) • 10w
we would distribute it to the 15c and the 8w
once we distribute it it would become
150cw because of 15c • 10w
and 80w^2 because of 8w • 10w
Answer:
Perimeter: 14.2
Area: 9.2
Step-by-step explanation:
Simple times for area
simple plus for perimeter
It’s 27 because u multiple the first 2 number and it’s a negative then add the rest to it
