Answer:

Below.

Step-by-step explanation:

( x + 2/5)(x + 3/7) = 0  will give x = -2/5, -3/7.

= x^2 + 2/5x + 3/7 x + ( 2^5 * 3/7) = 0

x^2 + (29/35)x + 6/35 = 0

Multiply through by 35:

35x^2 + 29x + 6 = 0 is the required equation.

To solve we factor it:

(7x + 3)(5x + 2) = 0

7x + 3 = 0 or 5x = 2 = 0

x = -3/7 , -2/5.
