Question

My question is :-
Prove that 5-2 = 4

Answer 1

5 - 2 = 4

both side multiply by 0

( 5- 2) × 0 = 4 × 0

0 = 0

LHS = RHS

# $¡nu

it is possible

Answer 2

Answer: Mathematically IMPOSSIBLE, equation is wrong.

Step-by-step explanation:

Given, expression is [(5 - 2) = 4]

To Find: Proof of the above mentioned expression.

Explanation:

• LHS or the Left Hand Side of our concerned equation is a basic subtraction, (5 - 2).
• Now, we can demonstrate (5 - 2) in a visually clear manner, very easily.
• 5 = 1 + 1 + 1 + 1 + 1, i.e., addition of Five 1s.
• And, 2 = 1 + 1, i.e., addition of Two 1s.
• Then, $(5 - 2) = [(1 + 1 + 1 + 1 + 1) - (1 + 1)]$

             or, (5 - 2) = [1 + 1 + 1 + {(1 + 1) - (1 + 1)}]

             or, (5 - 2) = [1 + 1 + 1 + {(1 - 1) + (1 - 1)}]

             or, (5 - 2) = [1 + 1 + 1 + (0 + 0)]

             $or, (5 - 2) = (1 + 1 + 1 + 0)$

             or, (5 - 2) = (1 + 1 + 1), i.e., addition of three 1s.

             or, (5 - 2) = 3.

• But, the RHS or Right Hand Side of our concerned equation is a direct integer, "4".
• Since, (3 ≠ 4), thus, (LHS ≠ RHS) or, [(5 - 2) ≠ 4] of our concerned expression.
• Hence, the expression [(5 - 2) = 4] is MATHEMATICALLY WRONG.

Without actual division, prove that $(x^2 - x - 2)$ divides $(2x^4 + x^3 - 5x^2 - 8x - 4)$.
