What is the least common multiple of 9a and 15a2 .?
lcm(9a, 15a²) = 45a² Factorising: 9a = 3² × a 15a² = 3 × 5 × a² lcm = 3² × 5 × a² = 45a²
Tx plus 2t plus hx plus 2h?
What does the question ask? Does it ask you to simplify the above, or is it part of a larger question where values for t, x and h are given? Is it definitely Tx rather than tx? If asked to simplify it, there are numerous ways to do so (but none really make it 'simpler' as such, so it is a bit of a strange one). For example, by factorising: tx + 2t + hx + 2h = t(x + 2) + h(x+2) or we could write (again by factorising) tx + 2t + hx + 2h = x(t + h) + 2(t + h) Which is useful depends on what the question asks, really.
Can you Factorise 4x²-9?
It is possible to factorise 4x²-9 further.Factorising is to express a number or expression as a product of factors.The technique of factorising two terms: a² - b² = (a + b) (a - b)If we apply ( 4x²-9 ) to the previous technique: 4x² - 9 = (2x + 3) (2x - 3)

How do you factorise 15x-27xy?
Factorising 15x-27xy gives 3x (5 - 9y).Factorising is to express a number or expression as a product of factors.When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)

When you use greatest common factor is it multiplying?
No, it is not. It is factorising - which is more related to dividing.
Where is division used?
In factorising division is used . It is used in opposite cases concern with multipling
How do you check math factorizations?
Multiply the factors together. If the answer is the number you were factorising, the process checks out and if not, there is an error.
