Answer:

mark me brilliant please

Answer 2

Answer:

3x - 6

x+5

Step-by-step explanation:

3x²-21x+30

   x²-25

take 3 as common from the numerator

3(x²-7x+10)

 (x)² - 5²

use identities and simplify

1. Splitting the middle term for 7x

numerator: 10 multiplied by x = 10x so the product must be 10 and the sum must be 7

denominator: a² - b² = (a+b)(a-b)

3(x²-5x-2x+10)

    (x)² - 5²

3(x²-5x-2x+10)

    (x+5)(x-5)

take common from numerator

3(x (x-5) -2 (x-5))

    (x+5)(x-5)

3(x-5)(x-2)

(x+5)(x-5)                         cancel (x-5)

3(x-2)

(x+5)

You can simplify further if you want

it will be equal to 3x - 6/ x+5
