To factor x^2 + 2x - 8 follow these steps


1) Write to factors, with x as the first term, this way:

(x      )(x      )


2) The sign to the right of the x in the first factor is the same sign of the coeficient of x in the polynomial.

That is +.


The sign to the right of the x of the second factor is the product of the sign of the coefficent of x (this is +) and the sign of the independent term (this is - ).

So that is (+).(-) + -.

Now the two factors have this form:

(x +  ) (x  -  )


3) Now find two numbers whose product is - 8 and whose difference is +2


Those numbers are + 4 and -2.


Then the two factors are:

(x + 4) (x -  2).


So the answer if that the correct factorization is (x + 4) (x - 2)

What is the median of 1, 3, 6, 8, 9, 9<br> Answer choices: A. 6<br> B. 7<br> C. 8<br> D. 9
luda_lava [24]

Answer:

B

Step-by-step explanation:

The median is the middle value of the data arranged in ascending order. If there is no exact middle value then it is the average of the values either side of the middle.

1,  3,  6,  8,  9,  9

           ↑ middle

median = \frac{6+8}{2} = \frac{14}{2} = 7 → B

Equation practice with angle addition
Triss [41]

Answer:

36 degrees

Step-by-step explanation:

since, m<AOB is a right angle, we shall just create an equation:

M<AOB+M<BOC=90 degrees

Substitute: 6z-12+3z+30=90

Solve: 6z+3x=9z

-12+30=18

so, 9z+18=90 degrees

           -18  -18

9z=72

z=8

So if z=8, then we should fit it so that it matches measure of AOB.

6z-12

6 times 8=48

48-12= 36
