Answer:
no
Step-by-step explanation:
For the equation:
-1=5 x^2 - 2 x
5 x^2 - 2 x + 1 = 0, then we substitute: a=5, b=-2, c =1
to discriminant formula: D= b^2 - 4 a c = (-2)^2 - 4 * 5 * 1 = 4 - 20 = - 16
Answer:
The discriminant is equal to -16 which means the equation has no real number solutions.
Answer:
i thinks its -9
Step-by-step explanation:
448.80 is the price but let’s not add the sales tax 476.85
X^2 = 24^2 + 7^2
x^2 = 576 + 49
x^2 = 625
x = 25
