-4x+5 factorise the polynomial plz
TPS:
take -5 as the constant term.
if you take +5, the roots will be complex numbers...
o I think the question would be x^{2} - 4x - 5
yeah...
yeah done. Thanks for suggestions, :)

x ² - 4x - 5
⇒ x ² - 5x + x - 5.
⇒ x ( x - 5 ) + 1 ( x - 5 )
⇒ ( x+ 1 ) ( x - 5 ).
Hence, ( x + 1 ) and ( x - 5 ) are the factors.
PS. Probably your question has some mistakes. The constant should be ( - 5 ).
( + 5 ) will give complex roots.
