Question

-7x+x^2 = ? Сколько будет?

Answer 1

-x(7-x) изи просто выносишь -х за скобку и все

Answer 2

To find the value of the expression -7x + x^2, you need to substitute a value for "x." Without a specific value for "x," we cannot calculate the exact result. The expression is in the form of a quadratic equation, and the result will depend on the value of "x."

If you provide a specific value for "x," I can help you find the answer. For example, if "x" is 2, we can calculate:

-7(2) + (2)^2 = -14 + 4 = -10

But without a specific value for "x," the expression remains as it is: -7x + x^2.
