sdas [7]

Answer:

2x^3-11x^2+16x-3

Step-by-step explanation:

Given expression,

(x - 3)(2x^2 - 5x + 1)

By distributive property,

x(2x^2-5x+1) - 3(2x^2-5x+1)

Again by distributive property,

2x^3-5x^2+x-6x^2+15x-3

Combining like terms,

2x^3-11x^2+16x-3

Which is required product.

Solve the equation using elimination. Write your answer as an ordered pair.
IgorLugansk [536]

Answer:

(-3, 1).

Step-by-step explanation:

2x + 7y =  1        -------------(A)

x + 5y  =  2       Multiply this by -2:

-2x - 10y = -4    Add this equation to equation (A):

0 - 3y = -3

3y = 3

y = 1.

Substitute this in equation (A):

2x + 7(1) = 1

2x = -6

x = -3.

Check if these 2 values are correct in the second equation:

-3 + 5(1) = 2

2 = 2.
