Question

Multiply and simplify. Show work/steps
(x-3)(x-4)

Answer 1

( x + a ) ( x + b ) = x^2 + ( a + b ) x + ab

( x + 3 ) ( x - 4 )

here a = 3 and b= -4

then

( x + 3 ) ( x - 4 ) = x^2 + ( 3 - 4 ) x + 3 * ( - 4 )

.........................= x^2 - x - 12

Answer 2

x(x-4)-3(x-4) EXPAND :)

Answer 3

x + a ) ( x + b ) = x^2 + ( a + b ) x + ab

( x + 3 ) ( x - 4 )

here a = 3 and b= -4

then

( x + 3 ) ( x - 4 ) = x^2 + ( 3 - 4 ) x + 3 * ( - 4 )

( x + 3 ) ( x - 4 )= x^2 - x - 12
