(x+3)^2=x^2+2x3+3^2

Solution

(x + 3)^{2} = x^{2} + 2 \cdot x \cdot 3 + 3^{2}

Solution

True for all x

Solution steps

(x + 3)^{2} = x^{2} + 2 x \cdot 3 + 3^{2}

Multiply the numbers:

2 \cdot 3 = 6

(x + 3)^{2} = x^{2} + 6 x + 3^{2}

3^{2} = 9

(x + 3)^{2} = x^{2} + 6 x + 9

Expand

(x + 3)^{2} : x^{2} + 6 x + 9

x^{2} + 6 x + 9 = x^{2} + 6 x + 9

Move

9

to the right side

x^{2} + 6 x = x^{2} + 6 x

Subtract

x^{2} + 6 x

from both sides

x^{2} + 6 x - (x^{2} + 6 x) = x^{2} + 6 x - (x^{2} + 6 x)

Simplify

0 = 0

Both sides are equal

True for all x
