What is the GCF of 42x 28y?
1 Expert Answer To find the GCF, do the prime factorization of both numbers. The GCF uses the numbers that appear in BOTH, 2 x 7 = 14 is the GCF of the numbers.
What is the GCF of 60x and 84?
The GCF of 60 and 84 is 12.
What do 21 and 45 have in common?
The common factors of 21 and 45 are 3, 1, intersecting the two sets above. In the intersection factors of 21 ∩ factors of 45 the greatest element is 3. Therefore, the greatest common factor of 21 and 45 is 3.
How to factorize 2x into two numbers in GCSE?
= 12y² – 18y – 2y + 3 [here the 20y has been split up into two numbers whose multiple is 36. 36 was chosen because this is the product of 12 and 3, the other two numbers]. The first two terms, 12y² and -18y both divide by 6y, so ‘take out’ this factor of 6y. We need to split the 2x into two numbers which multiply to give -8.
Is there any other way to factorise two squares?
Unfortunately, the only other method of factorising is by trial and error. The Difference of Two Squares If you are asked to factorise an expression which is one square number minus another, you can factorise it immediately. This is because a² – b² = (a + b) (a – b).
How to factor expressions in a factor calculator?
How to factor expressions 1 Add up to 5 2 Multiply together to get 4 More …
Which is the easiest way to factorise a number?
The first two terms, 12y² and -18y both divide by 6y, so ‘take out’ this factor of 6y. We need to split the 2x into two numbers which multiply to give -8. This has to be 4 and -2. Once you work out what is going on, this method makes factorising any expression easy.
