$a^{2} - a^{2} = a^{2} - a^{2}$

Step 1

Move all the expressions to the left side of the equation.

Tap for more steps...

Step 1.1

Subtract $a^{2}$ from both sides of the equation.

$a^{2} - a^{2} - a^{2} = - a^{2}$

Step 1.2

Add $a^{2}$ to both sides of the equation.

$a^{2} - a^{2} - a^{2} + a^{2} = 0$

Step 2

Combine the opposite terms in $a^{2} - a^{2} - a^{2} + a^{2}$ .

Step 2.1

Subtract $a^{2}$ from $a^{2}$ .

$0 - a^{2} + a^{2} = 0$

Step 2.2

Add $- a^{2}$ and $a^{2}$ .

$0 + 0 = 0$

Step 2.3

Add $0$ and $0$ .

$0 = 0$

Step 3

Since $0 = 0$ , the equation will always be true.

Always true
