Answer:
Question :-
Factorize -
\sf 2t^2 + 5t - 12 2t
2
+5t−12
Answer :
By using the middle term splitting method -
\sf 2t^2 + 5t - 12 2t
2
+5t−12
\sf = 2t^2 + 8t - 3t - 12 =2t
2
+8t−3t−12
\sf = 2 ( t^2 + 4t ) - 3( t + 4)=2(t
2
+4t)−3(t+4)
\sf = 2t ( t + 4 ) - 3(t + 4)=2t(t+4)−3(t+4)
\sf = ( 2t - 3)(t + 4)=(2t−3)(t+4)
\boxed{\sf 2t^2 + 5t - 12 = (2t - 3)(t+4)}
2t
2
+5t−12=(2t−3)(t+4)

Types of Factorization -
(a) Factorization by taking out the common factor :-
When each term of an expression has a common factor, divide each term by this factor and take out as a multiple.
(b) Factorization by grouping
(c) Factorization by making a prefect square
(d) Factorization the difference of two squares.
(e) Factorization of a quadratic polynomial by splitting the middle term
