Answer 1

Answer:

x = 1/3 and -5

Step-by-step explanation:

hello friend

given 3x² + 14x - 5 = 0

3x²+15x-x-5 = 0

3x(x+5) -1(x+5) = p

(3x-1)(x+5) = 0

3x-1 = 0

= 3x = 1 x = 1/3

and

x + 5 = 0

x = -5

Answer 2

Answer:

X = 5 or X = - 1/3

Step-by-step explanation:

Solve using zero product rule :-

3x² + 14x - 5

⇒ 3x² – 14x – 5 = 0

⇒ 3x² – 15x + x – 5 = 0 (taking common out)

⇒ 3x(x – 5) + 1(x – 5) = 0

⇒ (3x + 1)(x – 5) = 0

3x = -1 or x = 5

X= -1/3
