Question 27365
You solve this by the FOIL method;
First;
Outside;
Inside;
Last;
Now multiply this according to thewe words;
( 8x - 3)(5x - 4)
First multiply 8x*5x={{{40x^2}}}
Now multiply Outside; 8x*-4=-32x
Inside; -3*5x=-15x
Last; -3*-4=12
Now but those together in same order;
{{{40x^2}}}-32x-15x+12
add like terms;
{{{40x^2}}}-47x+12
Hope you understand
=)
