The standard form for this equation would be y = 2x^2 - 4x -1. This can be computed by expanding first the (x - 1)^2 which is x^2 - 2x +1. Then this will be multiplied by 2 which will give us, 2x^2 - 4x +2. Lastly, we will deduct the 3 from the equation which gives us the final answer of y= 2x^2 - 4x -1.

A wire with a length of 100 cm is cut into three parts. The length of wire of the first and second parts are the same. The lengt
dsp73

The first two pieces are the same, let each of those equal x, so you have x + x = 2x

The 3rd piece is the sum of the first two + 4, so this would be 2x + 4

Now you have 2x + 2x + 4 = 100 cm

Combine like terms:

4x +4 = 100

Subtract 4 from both sides

4x = 96

Divide both sides by 4

X = 24

First piece is 24 cm

Second piece is 24 cm

Third piece is 52 cm
