How is 6 a solution for 2x^2+4x=3+3x^2

weqwewe [10]

2x^2+4x-3-3X^2=0
simplify 2x^2+4x-3-3x^2 to -x^2+4x-3
-x^2+4x-3=0
Multiply both sides by -1
x^2-4x+3=0
Factor x^2-4x+3
1. Ask: Which two number add up to -4 and multiply to 3.
2. Answer:3 and -1.
3. Rewrite the expression as (x-3)(x-1):
(x-3)(x-1)=0
5Solve for x
1.Ask: when will (x-3)(x-1) equal zero.
2.Answer: when x-3=0 or x-1=0.
x=3,1

Answer:

steps below

Step-by-step explanation:

Vertex of Shape I : (1,1) (2,1) (2,2) (1,2) ---- (x,y)

Vertex of Shape II : (3,3) (6,3) (6,6) (3,6) ---(x',y') : (x*3 , y*3)

Vertex of Shape III : (2,2) (4,2) (4,4) (2,4) --- (x'',y'') -> (x' , y') : (x''*1.5 , y''*1.5)

Shape I dilate on to Shape II: Enlargement with scale factor of 3

dilation the Maps shape lll onto shape ll : Enlargement with scale factor of 1.5
