An equation
what else could it be?
<span>-2x^2-x+7=0
Variable with the highest degree's (exponent) constant, -2 is a, next variable's constant, -1 is b, the constant or number without a variable, 7 is c
using substitution put the numbers into the formula
</span>(-b±√(b^(2)-4ac))/(a^(2))
(-(-1)±√((-1)^(2)-4(-2)(7))/((-2)^(2)) simplify
(1±√(1+56))/4
1±√(57)/4 is your answer
There combined in come would be <span>68,745 if you put them together i dont know if thats one of the awnsers but i think that should be right
</span>
Answer:
c. Rational
because → whole numbers are positive and Starts from 0 so not whole number
Integers can be negative and positive
Examples of numbers that are not integers are: -1.43, 1 3/4, 3.14, . 09, and 5,643.1.
Irrational number that cannot be written in p/q
but -2.4 written in p/q = -24/100
<h3>so c. Rational Number is correct</h3>
