Answer:

-x^2+2x-3

Step-by-step explanation:

The given polynomial expression is

(x^2-3x)+(-2x^2+5x-3)

We regroup the terms in the polynomial to obtain;

x^2-2x^2-3x+5x-3

We combine like terms to get;

-x^2+2x-3

When we arrange the terms in the polynomial in descending powers of x, then we say it is in standard form.

The simplified polynomial in standard form is  -x^2+2x-3

AC is tangent to circle O at point C. What is the length of OC
Sedaia [141]

Let OC is x, so OC=OB=x

{4}^{2}  + x^{2}  =  {(2 + x)}^{2}  \\ 16 +  {x}^{2}  = 4 + 4x +  {x}^{2}  \\ 12 = 4x \\ x = 3

Solve the following quadratic equations by completing the square.<br><br> y^2-14y+48=0
NISA [10]

Answer:

  y = 6 or 8

Step-by-step explanation:

1. Subtract the constant:

  y^2 -14y = -48

2. Add the square of half the y-coefficient:

  y^2 -14y +49 = -48 +49

Write as a square, if you like:

  (y -7)^2 = 1

3. Take the square root:

  y -7 = ±√1 = ±1

4. Add the opposite of the constant on the left:

  y = 7 ±1  =  6 or 8

The solution is y = 6 or y = 8.
