Need nowfind the discriminant of the following equation. 9x^2+12x+4=0

So to find the discriminant of a quadratic equation, the formula is b² - 4ac with a = x² coefficient, b = x coefficient, and c = constant. In this case, our equation is

Firstly, solve the multiplications and the exponents:

Next, subtract and we find that our discriminant is 0.

*Additional Info: Since the discriminant is zero, this means that this quadratic equation has 1 real solution.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
