Question

x²+12x+27 upon x²+2x-3​

Answer 1

Answer:

x²+12x+27 / x²+2x-3​ =  (x + 9) / ( x - 1)

Step-by-step explanation:

First, find the two numbers whose product is 27 and sum is 12

Two numbers are 9 and 3

So x²+12x+27  = x²+9x+ 3x + 27

= x ( x + 9) + 3( x + 9)

= (x + 3) (x + 9)

Now, find the two numbers whose product is -3 and sum is 2

Two numbers are 3 and -1

x²+2x-3​ = x²+3x - 1x-3

= x ( x + 3) - 1 (x + 3)

= (x + 3) ( x - 1)

So, x²+12x+27 / x²+2x-3​ =  (x + 3) (x + 9) / (x + 3) ( x - 1)

=  (x + 9) / ( x - 1)

Answer 2

Step-by-step explanation:

(x+9) / (x- 1 )
