expand (3x^2-7)(3x^2-8)

expand

(3 x^{2} - 7) (3 x^{2} - 8)

9 x^{4} - 45 x^{2} + 56

Solution steps

(3 x^{2} - 7) (3 x^{2} - 8)

Apply FOIL method

(3 x^{2} - 7) (3 x^{2} - 8) : 9 x^{4} - 45 x^{2} + 56

= 9 x^{4} - 45 x^{2} + 56

k (s) + h_{2} \cdot o (l)

6 y^{2} + 21 y + 12

(- \frac{x}{2} + y + \frac{1}{4})^{2}

4 x y^{2} - x y^{2} - 7 x y^{2}

6 x y^{2} - 4 x^{2} y
