Can anyone help me to answer this question

0 or 6

Step-by-step explanation:

2aa = 12a

2a² = 12a

Subtract 12a from both sides.

2a² - 12a = 0

Factor left side of equation.

2a(a - 6)=0

Set factors equal to 0.

2a = 0

a =

a - 6 = 0

a = 6

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
