1) factor to see if you can get anything to cancel out before you multiply
2) the rest of my work is shown in the picture attached
3) the answer is n^2
Answer:
D. 49
Step-by-step explanation:
When completing the square, you take the value after x^2 which is 14 and divide it by 2 which equals 7 for which you then square that number which 7 times 7 = 49
J=30 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
12x² - 11x = 11
Can be rearranged to
12x² - 11x - 11 = 0
Where
a = 12
b = -11
c = -11
To find the discriminant, we do
b² - 4ac
Therefore, the discriminant is 649, which is greater than 0
Therefore the equation has two real irrational solutions.
