Answer:

Hans has done a mistake in the second step.

The correct answer is:

5x^2+13x-6=0

5x^2+15x-2x-6x=0 - 5. -6=-30 -30=15. -2

5x(1+3x)-2x(1+3x)=0

(5x-2x)(1+3x)=0

5-2x=0 1+3x=0

x=5/2 x=-1/3

kozerog [31]
Hello! One number is negative and the other one is positive. In this case, we should find the difference they are from 0 and add the numbers up. -11 is 11 units away from 0. 17 is 17 units away from 0. 11 + 17 = 28. The difference in temperature is 28 degrees Celsius.
