Solution: For this we substitute the value of x in the given equation and check LHS=RHS.
That is first we take LHS = 8x^{3}+2x^{2}+3x-5 and substitute the x value in LHS, we get
= 8(2)^{3} + 2(2)^{2} + 3.2 - 5
= 8.8 + 2.4 + 6 - 5
= 64 + 8 + 6 - 5
= 78 - 5
= 73
= RHS
Therefore LHS = RHS, so the given statement is True.
Directions: Check if the given statements are true or false. Also write at least ten examples of your own.
