Answer:
By checking it with multiplication
Step-by-step explanation:
You can use multiplication to check your division answer this way.
Do the division problem.
Multiply the quotient times the divisor.
If there is a remainder, add it to the multiplication product.
Compare this answer to the dividend. They should be the same number (630 = 630).
Put together the like terms, -k + kh + h. -k is -5 they are both negatives so it would be +5. 5 +kh +h. Next is 5 + -5 x -2. Two positives make a negative so it's 5 + -5 x -2, -5 x -2= 10 + 5 =15. so your answer is 15
For this case suppose that we have a quadratic equation of the form:

The solution to the quadratic recuacion is given by:

Where,
The discriminant is:

When the discriminant is greater than zero, then the root is positive, and therefore, we have two positive real solutions.
Answer:
B. it has two real solutions
