What is 2 times 3 times n times n = 54
kolezko [41]

If I'm reading this correctly, it is 2*3*n*n = 6n^2

6n^2 = 54  Divide by 6

n^2 = 54/6

n^2 =  9      Take the square root of both sides.

sqrt(n^2) = sqrt(9)

n = +/- 3

n = + 3 or n = -3. Both will solve the equation above.

Edit

2 * 3 * n * n

Let n = 3

2 * 3 * 3 * 3 = 6 * 9 = 54

The other value is n = - 2

2 * 3 * n * n

2 * 3 * (-3) * (-3)   A minus times a minus is a plus.

2 * 3 * 9 = 6 * 9 = 54

both + 3 and - 3 for n will give 54.
