Answer:
28x^2+3x-18
Step-by-step explanation:
Formula: (a+b)(a+b) = a^2 + a*b + a*b + b*b
Following this: 28x^2 -21x +24x -18
Then you combine like terms: 28^2 +3x-18
hope this helped!! :)
8=8,16,24,32,40,48,and so on
56= 56, 112, 168
It means an extra line needed to complete a proof/problem in plane geometry.
Answer:
-
or -
+8x-16
Step-by-step explanation:
Given a second degree polynomial has a root 4 with multiplicity 2
That means, 4 is a repeating root of the polynomial.
Any second degree polynomial has at most 2 real roots.
⇒Both roots of the polynomial are 4.
and its expression can be written as c·
where c is a real number
⇒c·(
-8x+16)
⇒c
-8cx+16c
Also, the leading coefficient is given as -1
So, c = -1
and the expression becomes (-1)
-8·(-1)·x+16·(-1)
⇒<u>-
+8x-16</u>
Yes there is a proportional relationship because the number of steps depend on the distance
