Question

find the roots of the equation 3x*2 +7x+2=0​

Answer 1

Answer:

Step-by-step explanation:

3x² +7x+2=0

3x*2 +6x+x+2=0​

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

(3x+1)(x+2)

x=-1/3

and x=-2

Answer 2

• 3x²+7x+2=0
• 3x²+6x+x+2=0 [By splitting middle term]
• (3x²+6x)+(x+2)=0
• 3x(x+2)+1(x+2)=0
• (3x+1)(x+2)=0

i.e.

3x+1 = 0 ; x+2 = 0

i.e. x = -1/3 ; x = -2

Therefore, roots of given equation are -1/3 & -2.
