The answer is A. 9, 12, 15,
Answer:
c (2,0) and (-2,0) I hope ot helps
Step-by-step explanation:
- -7.2(x-15.6)= -9
- -7.2x+112.32= -9
- -7.2x= -9-112.32
- -7.2x= -121.32
- x= -121.32/ -7.2
- x=16.85

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>
