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)
The largest rational number in the list is -6/5 and it is the third number line.
Answer:
well if you divide 40 3/8 by 10 1/4 you get 3.93
Step-by-step explanation:
Answer:
y=-3x-6
Step-by-step explanation:
(-4,6)
M=-3
y=mx+b
Substitute:
6=-3(-4)+b
Solve for B:
6=12+b
b=-6
Substitute B:
y=-3x-6
If not this then substitute the different varibles
Sorry if not correct :)
Answer:
Step-by-step explanation:
The difference of two squares:
a²-b² = (a - b) ( a + b)
a²-b² = a² + ab -ab +b²
