Simplify the expression
sasho [114]

Answer:

\frac{(x+1)}{5x}

Expression:

\frac{x^{2}-8x-9 }{5x^{2} -45x}

Factorise the expression:

<u>Numerator:</u>

x^2 - 8 - 9

Find a pair of factors of c, that summed, make b. And decide whether the numbers are positive or negative.

1 * 9 = 9

-1 * 9 = -9

1 * -9 = -9

-1 * -9 = 9

1 + 9 = 10

1 - 9 = -8

-1 + 9 = 8

-1 - 9 = -10

The factors are

(x+1) and (x-9)

<u>Denominator</u>

5x^2 - 45x

Remove the factor here is visible - 5x.

Divide the expression by 5x.

5x(x - 9)

Both expressions have a common factor - (x - 9). This will cancel out.

Now you're left with:

(x+1)/5x

\frac{(x+1)}{5x}
