Question

What are the factors of x^2 + x- 56

Answer 1

$Given \: Quadratic \: expression :$

$x^{2} + x - 56$

/* Splitting the middle term,we get */

$= x^{2} + 8x - 7x - 56$

$= x( x + 8 ) - 7 ( x + 8 )$

$= (x+8)(x - 7)$

Therefore.,

$\red{ Factors \: of \: x^{2} + x - 56 }$

$\green { = (x+8)(x - 7)}$
