Answer:
At first we have to multiply the co-efficient of x^2 with co-efficient of x^0 i.e, 3 × 6 = 18
After that,
factor of 18 = 2×3×3×1
Next,
with the help of all factor we have to find the the middle number i.e, 7
Next,
we can use any no. of times of multiplication but only one time of addition or subtraction
finally,
3×3 - 2× 1
= 9 - 2
= 7
3x^2 - 7x - 6 = 0
=> 3x^2 - (9x - 2x) - 6 = 0
=> 3x^2 - 9x + 2x - 6 = 0
=> 3x (x - 3) + 2 (x - 3) = 0
=> (x - 3 ) (3x + 2) = 0
Either,
x - 3 = 0
=> x = 3
or,
3x + 2 = 0
=> 3x = - 2
=> x = - 2/3
Answer:- (x = 3) & (x = - 2/3)
