A/ab-bsquare + b/ab-asquare?

lord [1]

Answer:

$\dfrac{(a+b)}{ab}$

Step-by-step explanation:

The given expression is :

$\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}$

It can be solved as follows :

$\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}=\dfrac{a}{b(a-b)}+\dfrac{b}{a(b-a)}\\\\=\dfrac{a}{b(a-b)}+\dfrac{b}{-a(-b+a)}\\\\=\dfrac{1}{a-b}(\dfrac{a}{b}-\dfrac{b}{a})\\\\=\dfrac{a^2-b^2}{ab(a-b)}\\\\=\dfrac{(a-b)(a+b)}{ab(a-b)}\\\\=\dfrac{(a+b)}{ab}$

So, the solution of the given expression is equal to $\dfrac{(a+b)}{ab}$ .

Factorise: 54x2 + 42x3 – 30x4

DerKrebs [107]

Answer:

Answer: x²(5 + 42x - 30x²)

Step-by-step explanation:

${ \tt{ {5x}^{2} + {42x}^{3} - {30x}^{4} }}$

» First factorise out x²:

$= { \tt{ {x}^{2}(5 + 42x - 30 {x}^{2} )}}$

» Then factorise the second bracket using quadratic knowledge:

${ \tt{ = {x}^{2}(5 + 42x - 30 {x}^{2} )}}$

» The second bracket can not be factorised further because its roots/zeros are not whole numbers
