Which equation is equivalent to (2x^2+4x-7)(x-3)

2 x^3 - 2 x^2 - 19 x + 21

Step-by-step explanation:

Expand the following:

(2 x^2 + 4 x - 7) (x - 3)

Hint: | Multiply out (x - 3) (2 x^2 + 4 x - 7).

| | 2 x^2 | + | 4 x | - | 7

| | | | x | - | 3

| | -6 x^2 | - | 12 x | + | 21

2 x^3 | + | 4 x^2 | - | 7 x | + | 0

2 x^3 | - | 2 x^2 | - | 19 x | + | 21:

2 x^3 - 2 x^2 - 19 x + 21

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
