Question

PX is equal to 8 square - 19 x minus 15​

Answer 1

$Given \:p(x) = 8x^{2} - 19x - 15$

/* Splitting the middle term, we get */

$\implies p(x) = 8x^{2} - 24x + 5x - 15\\= 8x( x - 3) + 5( x - 3 )\\= ( x - 5 )( 8x + 5 )$

Therefore.,

$\red { p(x) = 8x^{2} - 19x - 15} \green { = ( x - 5 )( 8x + 5 ) }$
