I need help with estimating, then finding the quotient and write the remainder if any as a fraction?

Answers

When estimating, you want to round the dividend and the divisor to the nearest time table number (i.e. 5700 --> 5400). Finding the quotient is easier when you estimate. Writing the remainder as a fraction is simple. First, get your remainder and your divisor, then make it to a fraction.

ex:

If you get a remainder of 3, and have a divisor if 12, your remainder would be 3/12, or 1/4.

Factor completely: 3x^2 – 21x + 30A. 3(x – 2)(x – 5)
B. (3x – 2)(x – 15)
C. 2(x – 3)(x – 10)
D. (x – 2)(x – 5)

Answers

The answer is going to be A.

You first factor 3 out getting x^2-7x+10

Then you factor that so (x-2)(x-5)  then tack that 3 onto the end so 3(x-2)(x-5)
a because 3(x^2-7x+10)
3(x-2)(x-5)
