It would be: b³ and 4ac. The equation containing these terms is the discriminant. The equation is b²-4ac. a, b and c are the first, second and third are the coefficients of the first, second and third terms of the quadratic equation, respectively.
Let's arrange the equation to the standard one first
2x² + 7x + 3 - 1 = 0 2x² + 7x + 2 = 0
b² - 4ac = (7)² - 4(2)(2) = 33
If the answer is a perfect square, then it can be factored. If not, like in this case, it can't be factored.
B= 2000 + CD 98000 = B + CD substitute b in 98000 = 2000 + CD + CD add variables 98000 = 2000 + 2CD subtract 2000 from each side 96000 = 2CD divide each side by 2 48000 = CD
