Answer:
The answer to your question is: (4, -1)
Step-by-step explanation:
M = midpoint (-1, 1)
A = (-6, 3)
B = (x, y)
x = 2xm - x1
x = 2(-1) + 6
x = -2 + 6
x = 4
y = 2ym - y1
y = 2(1) - 3
y = 2 - 3
y = -1

Answer:
Step-by-step explanation:
(a)
let, f(x) = 2x+1 & g(x) = 2x+2
So, f(x).g(x) = (2x+1).(2x+2) = 4x² + 6x + 2 = 2x+2 in
So, product of two 1 degree polynomials is a 1-degree polynomial in
(b)
let, f(x) = 2x³ - 3x² + 5x + 7 & g(x) = -2x³ + 3x² + x + 3 be two polynomials in R[x]
So, f(x) + g(x) = 6x + 10, which is a polynomial of degree 1 in R[x]
(c)
this is not possible, since, if f & g are 2 polynomials in any polynomial ring S, then, we always have,
deg(f.g) <= deg(f) + deg(g)
So, deg(f.g) = 5 (as desired) but, deg(f) + deg(g) = 2+2 = 4 but, 4 < 5
So, this is not possible.
So, no such example exists.
