Using the standard form ax^2 + bx + c = 0 of quadractic equation , solve 9x^2 = 49
+23247 If you are supposed to use the quadratic equation, you will need values for a, b, and c.
First, move the 49 to the left side by subtracting.
9x² = 49 then becomes 9x² - 49 = 0
Since the problems is missing the x-term, create an x-term, writing it as 0x and place it between the x² term and the number.
Now you have 9x² + 0x - 49 = 0
In the quadratic formula, a = 9 b = 0 c = -49
