Two times a number subtracted from its square equals 143. Find the number(s).
x^2 - 2x = 143
Thank you.
You're welcome.
are we looking for X OR the representation of the expression
we are looking for x, as indicated.
of course, to find x, you will need to come up with an equation to solve.
X=5 jk idk someone help???
To solve this problem, we can set up an algebraic equation. Let's assume the number is represented by 'x'.
According to the problem, "Two times a number subtracted from its square equals 143."
We can express this information using an equation:
x^2 - 2x = 143
To solve this equation, we need to rearrange it into a quadratic equation in standard form:
x^2 - 2x - 143 = 0
Now we have a quadratic equation that we can solve using factoring, completing the square, or using the quadratic formula.
Let's try factoring the quadratic equation:
(x - 13)(x + 11) = 0
Setting each factor equal to zero, we can find the possible values for x:
x - 13 = 0 or x + 11 = 0
Solving for x in each equation:
x = 13 or x = -11
So the possible solutions are x = 13 and x = -11. Therefore, the number(s) we're looking for are 13 and -11.
