Answer 2

Answer:

you should use the algebraic identity of (x+a) (x+b) = x square +(a+b)x +a×b

given,x=xonly ,a= -8, b= -10.

Step-by-step explanation:

step 1 :first write like a particular identity given above

(x-8)(x-10) =Xsquare +(-8+(-10)x +(-8 × -10)

now get the sum Xsquare-18x +80

therefore the answer is Xsquare-18x+80

(IF YOU WANT TO CHECK THIS ANSWER IS CORRECT OR WRONG YOU CAN ALSO CHECK BY DOING THE SPLITTING THE MIDDLE TERM OR FACTORISING XSQUARE-18X+80 WE GET (X-8)(X-10) IN SPLITTING THE MIDDLE TERM)
