Question

factorise these expressions
x²+4x-32

Answer 1

Answer:

x^2+8x-4x-32

x(x+8)+4(x+8)

x=-4, x=-8

Answer 2

Answer:

$\red { Factors \:of \: x^{2} + 4x - 32}$

$\green { = ( x + 8 )( x - 4 )}$

Step-by-step explanation:

$Given \: expression : x^{2} + 4x - 32$

/* Splitting the middle term, we get

$= x^{2} + 8x - 4x - 32 \\= x( x + 8 ) - 4( x + 8 )\\= ( x + 8 )( x - 4 )$

Therefore.,

$\red { Factors \:of \: x^{2} + 4x - 32}$

$\green { = ( x + 8 )( x - 4 )}$
