What two numbers multiple to get -12 and add to -5

Original question: What two numbers multiply to get -12 and add to -5.

Pairs of numbers (1.772, -6.772) and (-6.772, 1.772).

Step-by-step explanation:

Let and be the two numbers, the we know that

(1).

and

(2).

We solve for in equation(2) and substitute this into equation(1)

This is a quadratic equation, and its solutions are

we substitute these two solutions into equation(1) and find the corresponding values:

Thus we have two pairs of numbers which multiply to give -12 and add to give -5

and

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
