Use distributive property
5(4x + 3) - 2x
20x + 15 - 2x
Simplify by liked terms
18x + 15
The solution is A
Answer:
i) Equation can have exactly 2 zeroes.
ii) Both the zeroes will be real and distinctive.
Step-by-step explanation:
is the given equation.
It is of the form of quadratic equation
and highest degree of the polynomial is 2.
Now, FUNDAMENTAL THEOREM OF ALGEBRA
If P(x) is a polynomial of degree n ≥ 1, then P(x) = 0 has exactly n roots, including multiple and complex roots.
So, the equation can have exact 2 zeroes (roots).
Also, find discriminant D = ![b^{2} - 4ac = (-7)^{2} - 4(1)(3) = 49 - 12 = 37](https://tex.z-dn.net/?f=b%5E%7B2%7D%20%20-%204ac%20%3D%20%28-7%29%5E%7B2%7D%20%20-%204%281%29%283%29%20%3D%2049%20-%2012%20%3D%2037)
⇒ D = 37
Here, since D > 0, So both the roots will be real and distinctive.
Answer: 16
You divide 8 by 1/2 and you get 16 pieces
