Remember.
positive number x positive number = positive number
positive number x negative number = negative number
negative number x positive number = negative number
negative number x negative number = positive number
So if both numbers have the same sign, either both positive or both negative, then the product will be positive.
Answer:
512.5 and 5512.5
Step-by-step explanation:
p=5000,R=5%,T=3 comppund interest=p (1+R÷100)-1=5000×0.1025=512.5 again,amount=5000×1.1025=5512.5
2x^2 + x + 3=0 has only complex roots.
The determinant is 1-4*2*3 = -23
-23 (or any determinant) is the part under the square root sign, If that determinant is negative, knowing you cannot take the square root of a negative number, we know the answers must be complex.
