Multiply.
(v+3)(v-8)
simplify your answer.

v² -5v -24

Step-by-step explanation:

(v +3)(v - 8)

FOIL

Front

v x v = v²

Outer

v x -8 = -8v

Inner

3 x v = 3v

Last

3 x -8=-24

put it together in standard form (highest exponent to lowest)

v² - 8v +3v -24

combine like terms

v² -5v -24

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
