Question

What is the sum of the solutions to (x − 6)(x + 0.7) = 0 ?

Answer 1

Answer:

5.3

Step-by-step explanation:

(x − 6)(x + 0.7) = 0

using the zero product property

x-6=0   x+.7 =0

x-6+6 = 0+6       x+.7 -.7 = 0-.7

x = 6                   x= -.7

sum of the solutions

6+-.7 = 5.3

Answer 2

Answer:

$5.3$

Step-by-step explanation:

The solutions of the given equations are

$(x - 6)(x + 0.7) = 0\\\\\\x - 6 = 0 ; x = 6\\x + 0.7 = 0; x = -0.7\\x = 6, 0.7$

Difference between the two solutions of the equation is

$= 6 - (0.7)\\= 5.3$
