simplify (4t-1)(5t+3)-2t(10t-9)

simplify

(4 t - 1) (5 t + 3) - 2 t (10 t - 9)

25 t - 3

Solution steps

(4 t - 1) (5 t + 3) - 2 t (10 t - 9)

Expand

(4 t - 1) (5 t + 3) : 20 t^{2} + 7 t - 3

= 20 t^{2} + 7 t - 3 - 2 t (10 t - 9)

Expand

- 2 t (10 t - 9) : - 20 t^{2} + 18 t

= 20 t^{2} + 7 t - 3 - 20 t^{2} + 18 t

Group like terms

= 20 t^{2} - 20 t^{2} + 7 t + 18 t - 3

Add similar elements:

20 t^{2} - 20 t^{2} = 0

= 7 t + 18 t - 3

Add similar elements:

7 t + 18 t = 25 t

= 25 t - 3
