Question

while factorising x2+5x+4, the middle term can be splitted as ___ ( )
a)2x+3x b)x+3x+x c)x+4x d)2x+2x+x​

Answer 1

Answer:

5x will be split into x + 4x

Step-by-step explanation:

$x ^ { 2 } +5x+4=0$

$To \: solve \: the \: equation, \: factor \: x^{2}+5x+4 \: using \: formula\:</p><p>x^{2}\left(a+b\right)x+ab=\left(x+a\right) \left(x+b\right).\:</p><p> To \: find \: a \: and \: b, set \: up \: a \: system \: to \: be \: solved.$

a=1 b=4

5x will be split into x + 4x
