Question

(3x-7)•(0,7х+0,1)=0 Решите плиз

Answer 1

$2,1x^{2} +0,3x-4,9x-0,7; 2,1 x^{2} -4,6x-0,7$

Answer 2

To solve the equation (3x-7) * (0.7x + 0.1) = 0, we set each factor equal to zero and solve for x:

Step 1: Set the first factor equal to zero: 3x - 7 = 0

Step 2: Solve for x: 3x = 7 x = 7 / 3

Step 3: Set the second factor equal to zero: 0.7x + 0.1 = 0

Step 4: Solve for x: 0.7x = -0.1 x = -0.1 / 0.7 x = -1 / 7

So, the solutions to the equation are: x = 7 / 3 and x = -1 / 7.
