Solve the equation x, squared, minus, 8, x, minus, 43, equals, minus, 21x 2 −8x−43=−21 to the nearest tenth.
Question
Solution 1
The given equation is x^2 - 8x - 43 = -21.
First, we need to simplify the equation. We can do this by adding 21 to both sides of the equation to get rid of the negative sign on the right side. This gives us:
x^2 - 8x - 43 + 21 = 0
Simplify further to get:
x^2 - 8x - 22 = 0
