Mathematics

MAXImum [283]4 years ago

Answer:

Yes, it is a quadratic equation.

Step-by-step explanation:

<em>Let's solve it to make it a quadratic equation:</em>

=> \frac{x^2+1}{x^2} =5

=> x²+1 = 5x²

=> 5x²-x²-1 = 0

=> 4x²-1 = 0

<em>Comparing it with the standard form of quadratic equation i.e. </em>

ax^2+bx+c = 0

So, we get

a = 4 , b = 0 and c = -1

<u><em>So, yes. It is a quadratic equation and it is a pure quadratic equation since b is equal to 0.</em></u>

I think of a number, multiply by 2, subtract 6 and then divide by 4. If the answer is -8, what is the original number?
iVinArrow [24]

Answer:

-13

Step-by-step explanation:

you just start from -8 and work backwards.

so it's -8 multiply 4 to get -32, then add 6 to get -26, then divide 2 to get -13.

when you check from the beginning with -13, then it fits and the answer is -8!
