simplify (-6sqrt(7)y-9sqrt(7))^2

simplify

(- 67 y - 97)^{2}

252 y^{2} + 756 y + 567

Solution steps

(- 67 y - 97)^{2}

Apply Perfect Square Formula:

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

(- 67 y - 97)^{2} = (- 67 y)^{2} - 2 (- 67 y) \cdot 97 + (97)^{2}

= (- 67 y)^{2} - 2 (- 67 y) \cdot 97 + (97)^{2}

(- 67 y)^{2} = 252 y^{2}

- 2 (- 67 y) \cdot 97 = 756 y

(97)^{2} = 567

= 252 y^{2} + 756 y + 567

(3 X - 4 X^{2}) (6 X + 1)^{''}

- \frac{2 x ( x + 1 ) ^{2}}{3}

3 - sin (2 x^{2} - 3 x - 1) (4 x - 3)

(3 x^{2} + 3 y^{2} \frac{d y}{d x}) (x^{2} + y^{2})
