simplify (sqrt(x)+3)^2

Solution

simplify

(x + 3)^{2}

Solution

x + 6 x + 9

Solution steps

(x + 3)^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

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

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

(x)^{2} = x

2 x \cdot 3 = 6 x

3^{2} = 9

= x + 6 x + 9
