Step-by-step explanation:
Answer:
- 63
Step-by-step explanation:
f(x) = 1x² - 3x + 18
a =1, b= -3, c=18
D= b² - 4ac = (-3)² - 4*1*18 = - 63
Answer:
Step-by-step explanation:
Here the coefficients of this quadratic equation are {7, -1, -3}. Note that the given equation must be rewritten in standard form: 7x^2 - x - 3.
Then the discriminant, b^2 - 4ac, is (-1)^2 - 4(7)(-3), or 1 + 84, or 85. Because this discriminant is positive, the given quadratic has two real, unequal roots. These roots are:
-(-1) ± √85
x = ------------------
14
or:
1 ± √85
x = ------------------
14
