Factorizing the equation,
⇒6x²−29x+35=0
⇒6x²−14x−15x+35=0
⇒2x(3x−7)−5(3x−7)=0
⇒(2x−5)(3x−7)=0
⇒x= 2/5 , 3/7

6x²+29x+35=6x² + 14x + 15x + 35 = 0
= (6x² + 14x) + (15x + 35) = 0
= 2x (3x + 7) + 5 (3x + 7) = 0
= (2x + 5) (3x + 7) = 0
Thus, (2x + 5) = 0 or (3x + 7) = 0
So, x = -5/2 or x = -7/3
Let the zero of the given quadratic polynomial be -5/2 and -7/3.
Sum of zeroes = -5/2 + -7/3
= -15 - 14 / 6
= -29 / 6
=-(Coefficient of x)/Coefficient of x²
Product of zeroes = -5/2 × -7/3
= 35 / 6
=Constant term/Coefficient of x²
