Answer 1

Answer:

hey dear here is your answer....

In third line....

When we multiply..

(8x+3)×(x-5)

we multiply first the first bracket first to another bracket...

8x will be multiplied by second bracket I.e., (x-5)

then,

8x × x -8x× 5

8x^2-40x

similarly we multiply second no. with second bracket..then we got..

8x^2-40x+3x-15

hope it helps you dear...
