Question

Factorize: 2t^2-t-10

Answer 1

Answer:

(2t+5)(t-2)

Step-by-step explanation:

2t^2-t-10

= 2t^2-4t+5t-10

=2t(t-2)+5(t-2)

=(2t+5)(t-2)

Answer 2

Answer:

t = -2 OR

t = 5/2

Step-by-step explanation:

Let,

2t^2 - t - 10 = 0

2t^2 - 5t + 4t - 10 = 0

t (2t - 5) + 2 (2t - 5) = 0

(t + 2) (2t - 5) = 0

(t + 2) = 0 OR (2t - 5) = 0

t = -2 OR t = 5/2
