Question

(5-x) (3-2x) (4-3x)​

Answer 1

Step-by-step explanation:

$(5 - x)(3 - 2x)(4 - 3x) \\ (5(3 - 2x) - x(3 - 2x))(4 - 3x) \\( 15 - 10x - 3x + 2x {}^{2} )(4 - 3x) \\ 4(15 - 10x - 3x + 2x {}^{2} ) - 3x(15 - 10x - 3x + 2x {}^{2} ) \\ 60 - 40x - 12x + 8x {}^{2} - 45x + 30x {}^{2} + 9x {}^{2} - 6x {}^{3} \\ - 6x {}^{3} + 47x {}^{2} - 97x + 60$

Answer 2

Answer:

-28×^2-91×+60

Step-by-step explanation:

(5-×)(3-2×)=15-10×-3×+2×^2

=15-13×+2×^2

(15-13×+2×^2)(4-3×)=28×^2-91×+60
