6. Which of the following values are the zeroes of the expression 2x(x - 5)(x+7)? (1) {-7,0,5)
(3) {-5, -2,7}
(2) {-7, -2,5)
(4) {-5,0,7}

Step-by-step explanation:

To get the zeros of the expression 2x(x - 5)(x+7), we are going to equate the expression to zero and find the corresponding value of x as shown;

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

2x = 0

x-5 = 0

x+7 = 0

From 2x = 0

x = 0/2

x = 0

From x-5 = 0

x = 0+5

x = 5

From the equation x+7 = 0

x = 0-7

x = -7

Hence the values of the zeros are {-7, 0, 5}
