$\bf \textit{difference of cubes}
\\ \quad \\
a^3+b^3 = (a+b)(a^2-ab+b^2)\qquad
(a+b)(a^2-ab+b^2)= a^3+b^3 \\ \quad \\
a^3-b^3 = (a-b)(a^2+ab+b^2)\qquad
(a-b)(a^2+ab+b^2)= a^3-b^3\\\\
-------------------------------\\\\
\boxed{64=4^3}\qquad x^3+64\implies x^3+4^3\implies (x+4)(x^2-x4+4^2)
\\\\\\
(x+4)(x^2-4x+16)$

Please help me is this statement true or false 3(36 - 11) = 45?

viva [34]

Hi there! The answer is FALSE

To find the answer we need to work out the parenthesis.
$3(36 - 11) =$
$3 \times 36 - 3 \times 11 =$
$108 - 33 =$
$75$

75 does not equal 45 and therefore the statement is false.
