expand (*+2y+3z)^2

Solution

expand

(\cdot + 2 y + 3 z)^{2}

Solution

4 y^{2} + 12 yz + 9 z^{2}

Solution steps

(2 y + 3 z)^{2}

Apply Perfect Square Formula:

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

a = 2 y, b = 3 z

= (2 y)^{2} + 2 \cdot 2 y \cdot 3 z + (3 z)^{2}

Simplify

(2 y)^{2} + 2 \cdot 2 y \cdot 3 z + (3 z)^{2} : 4 y^{2} + 12 yz + 9 z^{2}

= 4 y^{2} + 12 yz + 9 z^{2}
