If: y = x2+20x+100 and x2-20x+100 Then: x2+20x+100 = x2-20x+100 So: 40x = 0 => x = 0 When x = 0 then y = 100 Therefore point of intersection: (0, 100)
It's not. For example, 52 + 9 = 34, which is not prime.
If by "what is the answer to" you mean "how do you factor", then the answer is as follows: x2 + 52x + 100 = x2 + 50x + 2x + 100 = x(x + 50) + 2(x + 50) = (x + 2)(x + 50)
It is: (x+1)(x+4) none of which are prime numbers
5x+x >100
X2 + y2 = 100 = r2 r = 10
x2 + x2 + x2 = (1 + 1 + 1)x2 = 3x2
No, as it has two factors, (x - 6)(x + 7)
(x - 10)(x - 10)
(x - 4)(x - 25)
x2-20x+100 = (x-10)(x-10) when factored
x2 + x2 = 2x2
