Hello from MrBillDoesMath!

Answer:

x = 0, +\-3

Discussion:

x^3 = 9x => subtract 9x from both sides

x^3 - 9x = 0 => factor x from both terms

x(x^2-9) = 0 => x = 0 or x^2 - 9 = 0

x = 0, +\-3

Thank you,

MrB

52 998 x 67 = (1,000 - 998) x 67

Tresset [83]

Given:

$\to \bold{52,998 \times 67 = (1,000 - 998) \times 67}$

To find:

Proving

Solution:

$\to \bold{52,998 \times 67 = (1,000 - 998) \times 67}$

Solving L.H.S part:

$\to \bold{52,998 \times 67}\\\\\to \bold{3,550,866}\\\\$

Solving R.H.S part:

$\to \bold{(1,000 -998) \times 67}\\\\\to \bold{(2) \times 67}\\\\\to \bold{ 134 }\\\\$

Therefore $\bold{L.H.S \bold{\neq} R.H.S}$
