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.

mamaluj [8]
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

RSB [31]

Answer:

k =4/5

Step-by-step explanation:

k - 4.8=0.32 - 5.4k\\\mathrm{Multiply\:both\:sides\:by\:}100\\k\times\:100-4.8\times\:100=0.32\times\:100-5.4k\times\:100\\\\Refine\\100k-480=32-540k\\\\Add\: 480\mathrm{\:to\:both\:sides}\\100k-480+480=32-540k+480\\\\Simplify\\100k=-540k+512\\\\\mathrm{Add\:}540k\mathrm{\:to\:both\:sides}\\100k+540k=-540k+512+540k\\\\Simplify\\640k=512\\\\\mathrm{Divide\:both\:sides\:by\:}640\\\frac{640k}{640}=\frac{512}{640}\\\\k=\frac{4}{5}
