Question

Solve by formula method : 3x²+7x+2=0​

Answer 1

Answer:

roots = -1/3, -2

Step-by-step explanation:

Formula =

$\frac{ - b \frac{ + }{ - } \sqrt{b ^{2} - 4ac } }{2a}$

b^2 - 4ac = 7^2 - 4×3×2 = 49-24=25

√b^2-4ac = √25 = 5

$\frac{ - 7±5}{6}$

= -7+5/6 and -7-5/6

= -2/6 and -12/6

=-1/3 and -2

This is the answer
