Question

a) 3 × X + 2 × X + X =

b) V × ( V + 2 ) + 2 =

c) A³ + 3 × A² + 3 × A + 1 =

d) N - 2 = 3 × N + 1 =

e) 2 × Y² - Y + 3 =

f) M³ + 2² = 3²

Answer 1

$a) \\ \\ 3 * x + 2 * x + x \\ \\ 3x + 2x + x \\ \\ 5x + x \\ \\ => 6x$

=====

$b) \\ \\ v * (v + 2) + 2 \\ \\ => v^2 + 2v + 2$

====

$c) \\ \\ a^3 + 3 * a^2 + 3 * a + 1 \\ \\ a^3 + 3a^2 + 3a + 1 \\ \\ => (a + 1)^3$

=====
$d) \\ \\ n - 2 = 3 * n + 1 \\ \\ n - 2 = 3n + 1 \\ \\ n - 2 - 3n -1 \\ \\ -2n - 3 (-1) \\ \\ 2n + 3 \\ \\ 2n = 3 \\ \\=> n = \dfrac{3}{2}$

====
$e) \\ \\ 2 * y^2 - y + 3 \\ \\ => 2y^2 - y + 3$

====

$f) \\ \\ m^3 + 2^2 = 3^2 \\ \\ m^3 + 4 = 9 \\ \\ m^3 + 4 - 9 \\ \\=> m^3 - 5$
