Complete Question: Mr. Brown and his 2 children are going to London by train. An adult ticket costs £24 and a child ticket costs £12. Mr. Brown has a family rail card which gives his 1/3 off adult tickets an...

Using the factorisation method. the factorised solution will look like (x+a)(x+b) = 0 by multiplying these two brackets we get the equation: x^2 + a.x+b.x + a.b = 0 so vomparing this to the equation in the q...

WORKING OUT 3a 3 b+12a 2 b 2 +9a 5 b 3 1) 3(a 3 b+4a 2 b 2 +3a 5 b 3 ) 2) 3a 2 (ab+4b 2 +3a 3 b 3 ) 3) Fully factorised: 3a 2 b(a+4b+3a 3 b 2 ) BRIEFLY EXPLAINED Factorising is the process of taking out any ...

To factorise 3a 3 b + 12a 2 b 2 + 9a 5 b 3 , we need to deal with like elements together.Start with the integers. The highest common factor of 3, 12, and 9 is 3. Therefore we factor out the 3 and the express...

To do this, we first need to calculate the prime factorisations of 432 and 522, that is to say we need to break the numbers down into their prime factors.Let's start with 432. 432 = 2 x 216432 = 2 x ( 2 x 10...
