Name the most efficient method to solve the quadratic equation: -2x^2+4=0

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
