Answer:
(x - 3/5) (x + 4/3)
Step-by-step explanation:
Assuming that the equation is 15x^2 and not 15 x 2, the problem proceeds as so:
Using the x method, multiply 15 by -12 and place that at the top of the x, 11 being placed at the bottom. In the x method, whatever two numbers multiply to produce the top number and add to give the bottom one are your factors.
Placing -180 at the top and 11 on the bottom, you get the numbers -9 and positive 20.
Setting up the first binomials as (x - 9) and (x +20), divide both constants by 15 as the original coefficient is not 1. This gives you 9/15 and 20/15 which simplify to the answers 3/5 and 4/3.
Answer:
-4
Step-by-step explanation:
-10 - (-6)
Remove the brackets:
-10 - - 6
Remember that all negative and negative values are always positive because they are the same; if they are different, for instance, a positive value and a negative value, then that value will be a negative value.
Continue solving:
-10 - - 6
- and - are positive values
- 10 + 6
= - 4
Therefore the answer is 4

Answer:
5x + y = 3/8
Step-by-step explanation:
Add to both sides
+ y = 3
Divide both sides by 8
5x + y = 3/8
