X² <span>+ 11x = -28
to find the solution of this polynomial, it'll be easiest to try and factor it. the first thing you need to do is move everything to one side:

</span>x² + 11x = -28 ... add 28
x² + 11x + 28 = 0 ... factor
(x + 7)(x + 4) = 0 ... now set both of your factors equal to zero and solve for x

x + 7 = 0
x = -7

x + 4 = 0
x = -4

A sold a commodity to b at 10% profit b again sold it to a at 10% loss. What does a have
ozzi
Let's answer this step-by-step.

First of all, let's estsblish the original price of the commodity as being 100%. Therefore:

Original price of commodity = 100%

Then, when A sold the commodity to B, it was sold at a 10% profit. Therefore:

Price of commidity when A sold to B:
100% x 1.1 = 110%

After that, when B sold it back to A, it was sold at a 10% loss. Therefore:

Price of commodity when B sold to A:
110% x 0.9 = 99%

Hence, A now has 99% of the original value of the commidity.
