You can put this solution on YOUR website! 7k^2 -9k -10,,,,,,,,,Factors of 7(7*1),,,factors of 10 (10*1,,,5*2),,,,,(-) last term means difference of factor multiples,,,,,,,,(-) middle term means largest factor multiple (-)
.
(7k +5)(k-2)
.
F = 7k*k = 7k^2
.
O = 7K *-2 = -14 k

I = k*5 = 5k
.
L= 5*-2= -10
.
combining middle terms,,,, 7k^2 -9k -10
