Basically you are trying to find two numbers that when they are added equals -2 and when multiplied equals -3. As you can see -3 plus +1 is equal to -2. And 1 times -3 equals -3. Therefore you have (x+1)(x-3). In order to check if these are the right numbers you will need to multiply (x+1)(x-3) and will end up with the first equation x^2-2x-3. Hope this helped! :)
I choose A 4x(x2 - 3x + 1)
21 × 10 = 210
210 ÷ 55 = 3.82
3.82 ÷ 10 =0.382
The model that represents -> 1.5+(-4) is model (B). Model B is the right answer because u start of with a positive 1.5 and then u have to add a (-4) which just means subtract it from 1.5.
5/14 is the difference between 3/7 and 1/14.
