5dx2 50dx 80d

Apr 2nd, 2015

5dx^2 + 50dx + 80d

first take common 5d from all the terms

= 5d( x^2+10x + 16)

Sum should be 10 

Product should be 16, the factors should be 8 and 2 .. because on adding 8+2 ...we get sum 10 and on multiplying ....we get 16 ....

= 5d( x^2 + 8x + 2x + 16)

= 5d(x(x+8)+2(x+8))

= 5d (x+8)(x+2)

this should be the answer
