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).

16
What is the solution to the two equations 2x - y equals 16 and -x plus 2y equals -8?
y = 0 and x = 8.
In parallelogram ABCD AB equals 12 BC equals 16 plus 2x what is x?
Anything you like (as long as it is > -16 so that BC > 0). In a parallelogram, adjacent sides do not impose any restrictions on one another.
What is the discriminant of the polynomial 9x2 - 18x 9?
The discriminant is 0.
9x2-18x plus 9 equals 0 what is the discriminant?
The discriminant is 0.
What are the solutions to this equation 9x2 plus 6x-7 equals 0?
9x2+6x-7 = 0 Using the quadratic equation formula:- x = 0.6094757082 or x = -1.276142375
What are the solutions to 9x2 plus 7x equals 2?
9x2 + 7x = 2 9x2 + 7x - 2 = 0 9x2 + 9x - 2x - 2 = 0 9x(x + 1) - 2(x + 1) = 0 (9x - 2)(x + 1) = 0 x ∈ {-1, 2/9}
9x2 - 6x plus k equals 0?
k = -3; factors are (9x + 3)(x - 1)
Solve 9x2 - 9x equals 0?
9x2-9x = 0 x2-x = 0 x(x-1) = 0 x = 1 or x = 0
Solve the quadratic equation using factoring 9x2 - 16 equals 0?
(3x+4)(3x-4)=0 x=±4/3
How do you factor this Y equals x³ plus 3x² - 10x-24 and Y equals -x³ -6x²-3x plus 10?
It can be simplified in the form of: 2x3+9x2-7x-34 = 0
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).
