16x^2 + 8x - 15

16x^2+8x-15 = (4x+5) (4x-3)

Hello:

16x² + 8x - 15 = 16 (x² + (1/2) x) - 15

= 16 (x²+1/2x+1/16-1/16) - 15

= 16 ((x+1/4) ² - 1/16) - 15

= 16 (x+1/4) ²-1-15

=16 (x+1/4) ²-16

=16 ((x+1/4) ²-1²)

=16 (x+1/4-1) (x+1/4+1)

=16 (x-3/4) (x+5/4)

=16/16 (4x-3) (4x+5)

Factor completely, is:

16x² + 8x - 15 = (4x-3) (4x+5)
