Answer: C. (0, -3)
Step-by-step explanation:
You don't even need to find the function, just mentally graph every point in the options on the graph.
- If it land in the white area, it's not a solution.
- If it land in the blue area or on the line, it's a solution.
<em>The line is not dotted, showing that the inequality is probably either ≥ or ≤, so points on the line do count as solution.</em>
Answer:
B. 5( 3n + 2 )...............
For zeroes of r1,r2,r3, the factors of the function, f(x) are
(x-r1)(x-r2)(x-r3)
zeroes of -3,-5,2
(x-(-3))(x-(-5))(x-2)=
(x+3)(x+5)(x-2)
f(x)=(x+3)(x+5)(x-2)
expanded
f(x)=x³+6x²-x-30
Answer:
2(x-1)(x-4)
Step-by-step explanation:
Begin by dividing each term by 2 and pulling the 2 to the front.
This is a trinomial. Trinomials are three term algebraic expressions typically featuring variables to exponent powers. To break these trinomials down we factor them using the diamond method or GCF. The diamond method states that for a trinomial 
multiply a*c then find two numbers which multiply to this number and add to b. When you find those numbers, write them as 
.
a=1, c=4
ac=4 and add to b=-5 which -1 and -4 satisfy
The factored form is 2(x-1)(x-4).
The triangles are similar because all pairs of corresponding angles are congruent.
