Which method is the most efficient method to use to solve x^2+5x-6=0

Factoring

Step-by-step explanation:

We have the function

To factor this expression we must look for two numbers a and b that when adding them give as a result 5 and multiplying them give as a result -6

Then the factorization will have the form

You can verify that:

So:

So:

The solutions are:

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
