Factorise the expression 3a2-4ab as far as possible

Mathematics
1 answer:
horsena [70]3 years ago

In this case, you have to find a common multiple of 3a^2 and 4ab. As only one of the numbers is divisible by two, this means that two cannot go outside of the bracket. The only other aspect that is in both sides of the equation is a, therefore, this goes outside the bracket. The best way to approach this is to divide both sides by a, and this will give you what is inside the bracket. 3a^2 divided by a is 3a, therefore, this is the first aspect in the bracket. -4ab divided by a, leaves -4b. Therefore, these go in the bracket.
3a^2- 4ab simplified is a(3a-4b)
Hope this helps

-3x + 4y = 12<br> 3x – 6y = 18<br> Answer has to be (x,y)
navik [9.2K]

Answer:

(24, -15)

Step-by-step explanation:

-3x + 4y = 12

3x – 6y = 18

Add the two equations together to first solve for y

-2y=30

y=-15

Enter -15 into one of the equations to solve for x

-3x + 4(-15) = 12

-3x-60=12

-3x=72

x=24

Hope this helps! Please mark brainliest :)
