expand (7x^2-yz)(3x^2+5yz)

expand

(7 x^{2} - yz) (3 x^{2} + 5 yz)

21 x^{4} + 32 x^{2} yz - 5 y^{2} z^{2}

Solution steps

(7 x^{2} - yz) (3 x^{2} + 5 yz)

Apply FOIL method

(7 x^{2} - yz) (3 x^{2} + 5 yz) : 21 x^{4} + 32 x^{2} yz - 5 y^{2} z^{2}

= 21 x^{4} + 32 x^{2} yz - 5 y^{2} z^{2}

(7 u)^{2}

2 (x + 4)^{2} - 6

2 (x + 4)^{2} - 3

2^{1 - 2}

- \frac{1}{5} - \frac{2}{3}
