What is the role of LCM and HCF in the addition and subtraction of algebric fraction |
|
Answer» se, the idea is the same for the ALGEBRAIC terms. But it's EASIER, because it's immediately CLEAR what the algebraic factors are:10ab3 = 2 x 5 x a x b x b x b = 5ab2 x 2b5a2b2 = 5 x a x a x b x b = 5ab2 x aFor numbers, finding a highest common factor can take a bit of work - it's harder to identify the factors of a number than the factors of an algebraic term. But the UNDERLYING mathematical concept is identical. Perhaps it might even be better to start with algebra before moving onto numbers.hope it will help you |
