Answer 1

Ответ:

1) (c+2)(c-3)=c^2-3c+2c-6=c^2-c-6

2) 25 x ^2 − 4 y^ 2

3) (2a-1)(3a+4)=6а^2+8a-3a-4=6a^2+5a-4

4) a^3-5a^2+12a-12

Answer 2

It looks like you've provided four algebraic expressions, and it seems you might want help with factoring or expanding them. Let's go through each one:

A) $(c + 2)(c - 3)$

To expand this expression, you can use the distributive property (FOIL): $(c + 2)(c - 3) = c(c) + c(-3) + 2(c) + 2(-3)$ Simplify this expression to get the expanded form.

B) $(5X - 2Y)(4X - Y)$

Again, use the distributive property to expand this expression: $(5X - 2Y)(4X - Y) = 5X(4X) + 5X(-Y) - 2Y(4X) - 2Y(-Y)$ Simplify to get the expanded form.

C) $(2a - 1)(3a + 4)$

Expand using the distributive property: $(2a - 1)(3a + 4) = 2a(3a) + 2a(4) - 1(3a) - 1(4)$ Simplify the expression.

D) $(a - 2)(a^2 - 3a + 6)$

Again, use the distributive property: $(a - 2)(a^2 - 3a + 6) = a(a^2) + a(-3a) + a(6) - 2(a^2) - 2(-3a) - 2(6)$ Simplify this expression to obtain the expanded form.
