How many x-intercepts does the graph of y equals 9x2 plus 30x plus 25 have?
Factorising, we have, 9x2+ 30x + 25 = (3x + 5)2;thus, when y = 0, x = -1⅔. This tells us that the sole x-intercept of this function is at the vertex, (0, 1⅔).

How do you factor this equation 9x2 plus 4?
Two possibilities here. 9x - 30x +25 = -21x + 25 and done, but I don't think you mean that. 9x² - 30x + 25 is more likely. This is easier than normal, since this follows the square pattern. (ax-b)² = a²x²-2ab+b² a² = 9 so a=3 b² = 25 so b=5 3*5*2 = 30, so it checks. (3x-5)(3x-5) = 9x² -15x - 15x + 25 = 9x² -30x + 25 ■

Is 9x2 plus 48xy plus 64y2 prime?
9x2 + 48xy + 64y2 = (3x + 8y)2. Since it is a squared number cannot be a prime. We can say that as a perfect square number, it is formed by the sum of 1 and some prime numbers (excluded 2), i.e 1 + 3 + 5 + 7 + 11 + ... n, where n is a prime.
