I'll go out on a limb here, and assume that you want a unit rate,
although technically, you haven't asked ANY question.

Example 2

Arada [10]

Answer:

y=x-2

Step-by-step explanation:

If you have drawn the graph of $y = x^2 - 3x + 1$ .

To determine the equation of the line which should be drawn to solve the equation: x² - 4x +3=0

Simply carry out the subtraction: $x^2 - 3x + 1 -(x^2 - 4x +3)$

$\implies x^2 -3x + 1-x^2 + 4x -3 \\= x^2 - x^2+ 4x - 3x-3 + 1\\=x-2$

The equation of the line which should be drawn is: y=x-2

What this means is simply:

$y = x^2 - 3x + 1$ and $y=x-2,$ then:\\x^2 - 3x + 1=x-2\\x^2 - 3x + 1-x+2=0\\x^2 - 4x + 3=0$

(x⁴ + 3x³ – 2x² + 5) + (2x⁴ – 5x³ + 4x – 15).

olya-2409 [2.1K]

Answer:

$\left(x^4+3x^3-2x^2+5\right)+\left(2x^4-5x^3+4x-15\right)$

$=$ $x^4+3x^3-2x^2+5+2x^4-5x^3+4x-15$

$=x^4+2x^4+3x^3-5x^3-2x^2+4x+5-15$

$=x^4+2x^4-2x^3-2x^2+4x+5-15$

$=3x^4-2x^3-2x^2+4x+5-15$

$=3x^4-2x^3-2x^2+4x-10$
