Multiply (7x-2)(-4x-3)
Use the "FOIL" method. Multiply the binomials in this order:
F = First - Multiply the first terms in each binomial together: (7x)(-4x)
O = Outer - Multiply the outer terms together: (7x)(-3)
I = Inner - Multiply the inner two terms together: (-2)(-4x)
L = Last - Multiply the last two terms together: (-2)(-3)
Then add them together:
(7x-2)(-4x-3) = (7x)(-4x) + (7x)(-3) + (-2)(-4x) + (-2)(-3)
= -28x2 - 21x + 8x + 6
Combine like terms:
= -28x2 - 13x + 6
