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

expand

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

21 x^{4} - 41 x^{2} + 10

Solution steps

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

Apply FOIL method

(7 x^{2} - 2) (3 x^{2} - 5) : 21 x^{4} - 41 x^{2} + 10

= 21 x^{4} - 41 x^{2} + 10

(\frac{3}{4} x - 2)^{2}

\frac{15}{99}

2 t^{3} - 11 t^{2} + 12 t + 9

\frac{3 i ^{171} + 2}{4 i - i ^{20}}

\frac{36}{- 3}
