Question

factorise the following:x2+5x-104 by using suitable identities​

Answer 1

$\huge\bf { \red S \green O \pink L \blue U \orange T \purple I \red O \pink N \green{...}}$

→ x² + 5x - 104

By splitting middle term

→ x² + 13x - 8x - 104

→ x ( x + 13 ) - 8 ( x + 13 )

→ ( x - 8 ) ( x + 13 )

Answer 2

x= -13 , 8

here is ur step-by-step explanation:

∆ x^2+13x-8x-104

∆ x(x+13)-8(x+13)

∆ (x+13)(x-8)
