Question

(x+1)(x-3)(x-4) find products​

Answer 1

(x+1)(x-3)(x-4)

= (x+1)[x(x-4)-3(x-4)]

= (x+1)(x²-4x-3x+12)

= (x+1)(x²-7x+12)

= x(x²-7x+12)+1(x²-7x+12)

= x³-7x²+12x+x²-7x+12

= 2x²-6x²+5x+12

Therefore.,

(x+1)(x-3)(x-4) = 2x²-6x²+5x+12

Answer 2

Answer:

x³-6x²-11x+12

Step-by-step explanation:

Multiplying first two brackets

(x²-3x+x-3)(x-4)

(x²-2x-3)(x-4)

(x³-4x²-2x²+8x-3x+12)

x³-6x²+5x+12
