Question

3x^2 + mx + 2 = 0 Find the value of m.

Answer 1

Answer:

Step-by-step explanation:

3x² + mx +2 =0

A= 3 , b = m, c=2

B² - 4ac = 0

M² - 4(3)(2) = 0

M² - 24 = 0

M² = 24

M= /24 = ± 2/6

Answer 2

Answer:

m=±2√6

Step-by-step explanation:

3x²+3mx-2mx+2=0

⇒using b²-4ac,

a=3,b=m,c=2.

⇒m²-4x3x2=0

⇒m²-24=0

⇒m²=24

⇒m=√24

⇒m=±2√6
