D=7, h= 199
D=8, h= 220
D=10, h= 262
Answer:
Distributive property
Step-by-step explanation:
3(2 − 3x) + 4x = x − 7
Distribute the 3 to each term in the parentheses using the distributive property
6 -9c +4x = x-7
The nature of roots of a quadratic equation can be determined from its discriminant.
Discriminant = b² - 4ac
b = coefficient of x term = 2
a = coefficient of squared term = 2
c = constant = 4
So,
Discriminant = 4 - 4(2)(4) = -28
Since the discriminant is negative, the two roots of the given equation will be complex .
Therefore, the answer to this question is option B
