expand (4t^2+t-7)(4t^2-1)

expand

(4 t^{2} + t - 7) (4 t^{2} - 1)

16 t^{4} + 4 t^{3} - 32 t^{2} - t + 7

Solution steps

(4 t^{2} + t - 7) (4 t^{2} - 1)

Distribute parentheses

= 4 t^{2} \cdot 4 t^{2} + 4 t^{2} (- 1) + t \cdot 4 t^{2} + t (- 1) - 7 \cdot 4 t^{2} - 7 (- 1)

Simplify

4 t^{2} \cdot 4 t^{2} + 4 t^{2} (- 1) + t \cdot 4 t^{2} + t (- 1) - 7 \cdot 4 t^{2} - 7 (- 1) : 16 t^{4} + 4 t^{3} - 32 t^{2} - t + 7

= 16 t^{4} + 4 t^{3} - 32 t^{2} - t + 7
