expand (3x-5)^2

Solution

expand

(3 x - 5)^{2}

Solution

9 x^{2} - 30 x + 25

Solution steps

(3 x - 5)^{2}

Apply Perfect Square Formula:

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

(3 x - 5)^{2} = (3 x)^{2} - 2 \cdot 3 x \cdot 5 + 5^{2}

= (3 x)^{2} - 2 \cdot 3 x \cdot 5 + 5^{2}

Simplify

(3 x)^{2} - 2 \cdot 3 x \cdot 5 + 5^{2} : 9 x^{2} - 30 x + 25

= 9 x^{2} - 30 x + 25
