What is the difference?
Whitepunk [10]

Answer:

\frac{x^2+3x  -12}{(x-5) (x +3)(x+7)}

Step-by-step explanation:

Given

\frac{x}{x^2-2x-15} - \frac{4}{x^2+2x-35}

Required

Calculate the difference

We start by factorizing the denominator of both fractions

\frac{x}{x^2-2x-15} - \frac{4}{x^2+2x-35}

\frac{x}{x^2+3x - 5x -15} - \frac{4}{x^2+7x - 5x-35}

\frac{x}{x(x+3) - 5(x +3)} - \frac{4}{x(x+7) - 5(x+7)}

\frac{x}{(x-5) (x +3)} - \frac{4}{(x-5)(x+7)}

Take LCM

\frac{x(x+7) - 4(x +3)}{(x-5) (x +3)(x+7)}

Open Brackets

\frac{x^2+7x - 4x -12}{(x-5) (x +3)(x+7)}

\frac{x^2+3x  -12}{(x-5) (x +3)(x+7)}

This can't be simplified any further;

If function / is defined by f(x) = x2 - 2x + 6
salantis [7]

Answer:

21

Step-by-step explanation:

Start with the inside first.

The inside is g(3).

g(3) can be found by using function, g.

g(x)=3x-4 so g(3)=3(3)-4=9-4=5.

So now we have that:

f(g(3))

f(5)

We can find f(5) by replacing x in the expression x^2-2x+6 with 5:

(5)^2-2(5)+6

25-10+6

15+6

21

This means f(g(3))=f(5)=21
