yea. im stuck at the -x-20/8x+16
numerator:what re the two numbers when added give you -1 and when multiplied give you -20. denominator:what are the two numbers when added together give you 8 and when multiplied give 16? \[X^2-5X+4X-20/X^2+4X+4X+16\]
CANCEL (X+4) FROM TOP AND BOTTOM ,YOU ARE left with \[(x-5)/(x+4)\]
