-2x^2+4x-1 from 6x^2+3x-9

kirza4 [7]

Answer:

$8{x}^{2} - x - 8$

Step-by-step explanation:

We want to subtract

$- 2 {x}^{2} + 4x - 1$

from

$6 {x}^{2} + 3x - 9$

We set up the subtracttion problem to get:

$6 {x}^{2} + 3x - 9 - ( - 2 {x}^{2} + 4x - 1)$

We expand the parenthesis to get:

$6 {x}^{2} + 3x - 9 + 2 {x}^{2} - 4x + 1$

Group similar terms:

$6 {x}^{2} + 2 {x}^{2} + 3x- 4x + 1 - 9$

We simplify to get:

$8{x}^{2} - x - 8$

Alex73 [517]

Drew = 5 3/8
Collin = 8 5/12

$\text {Difference = } 8\dfrac{5}{12} - 5\dfrac{3}{8} = 8\dfrac{10}{24} - 5\dfrac{15}{24} = 7\dfrac{34}{24} - 5\dfrac{15}{24} = 2\dfrac{19}{24}$

$\text {Answer : } 2\dfrac{19}{24}$
