Question

Multiply: (5t - 3)(2t - 4). Use ^ to indicate an exponent.



Multiply: (m - 5)(m + 9)

Answer 1

\[5t(2t-4)-3(2t-4)= 10t^2-20t-6t+12\]

Answer 2

use foil
first outside inside last

first ---------m x m
outside -------- m x 9
inside---------- m x (-5)
last -----------(-5) x (9)

m^2 + 9m -5m -45 combine like terms
m^2 + 4m-45

use this and model and multiply other binomials.....

Answer 3

thankyou!
