Question

What should be added to 2x-3x + 6 to get 4x^2- x + 2?​

Answer 1

Answer:

$4x^{2}$  - 4

Step-by-step explanation:

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

= $4x^{2}$ - x + 2 - 2x + 3x - 6

= $4x^{2}$  - 4

or 4 ($x^{2}$ - 1)

Answer 2

Answer:

(2x-3x+6)+ b= 4x∆2-x+2

Step 1= add x to both sides

b-x+6+x=4x∆2+2

Step 2= add-6 to both sides

b+6+-6=4x∆2+2+-6

therefore=4x∆2-4

answer=4x∆2-4
