Solution:
The difference of cubes identity is
if a and b are any two real numbers, then difference of their cubes , when taken individually:
→a³ - b³= (a-b)(a² + a b + b²)→→→Option (D) is true option.
I will show you , how this identity is valid.
Taking R H S
(a-b)(a² +b²+ab)
= a (a² +b²+ab)-b(a² +b²+ab)
= a³ + a b² +a²b -b a² -b³ -ab²
Cancelling like terms , we get
= a³ - b³
= L H S

Just plug numbers and it will give you graph attributes
Answer:
a = 2
b = 3
c = -5
Step-by-step explanation:
We are given Algebraic expression:
5-3x = 2x²
We rewrite it in standard form
2x² + 3x - 5
Algebraic form :
ax² + bx + c
Hence, the values of a, b, c is given below:
a = 2
b = 3
c = -5
