Answer:
Step-by-step explanation:
=6x²-7x-3
=6x²+2x-9x-3
=2x(3x+1)-3(3x+1)
=(2x-3)(3x+1)
⇒2x-3=0 or ⇒3x+1=0
⇒x=3/2 or ⇒ x= - 1/3
α=3/2 ,β= - 1/3
⇒α+β= -b/a
⇒3/2+(-1/3)= - (-3)/6
⇒3/2-1/3=1/2
⇒7/6 =1/2
⇒αβ=c/a
⇒ 3/2(-1/3)= -7/6
⇒-1/2= -7/6
⇒1/2=7/6

Answer: Hope its helpful
Step-by-step explanation: a=6 , b = -9 , c = -3
6x^2 -7x-3 = 0
6x^2 -9x +2x -3 = 0
3x(2x-3) + 1(2x-3) = 0
3x+1 = 0 and 2x-3 = 0
X= -1/3 X= 3/2
I'm taking a and b for alpha and beta
a+b =-b/a
-1/3+3/2 = -(-7)/6
-2+9/6 = 7/6
7/6 = 7/6
ab = c/a
-1/3×3/2= -3/6
-3/6 = -3/6
Hence, verified.
