17. Factorise :- 2x2 + 7x +3.​

Answer 1

Answer:

7(1+x)

Step-by-step explanation:

2 × 2 + 7x + 3

= 4 + 7x + 3

= 7 + 7x

= 7(1+x)

Answer 2

Step-by-step explanation:

2x²+7x+3

2x²+7x+3= 0

Lets split the middle term by taking the lcm of a and c i.e 2 and 3

2x²+6x+x+3=0

2x(x+3)+1(x+3)= 0

(2x+1)(x+3)=0

Either 2x+1=0

2x=-1

x= -1/2

or, x+3= 0

x=-3
