Question

2) (2 - a) (16 - a + a²);4) (5 – b)(4 - 6 - 62);​

Answer 1

Ответ:

2) -а³+3а²-18а+32.

4) 64b-320.

Объяснение:

2) (2-а)(16-а+а²)= 32-2а+2а²-16а+а²-а³= -а³+3а²-18а+32.

4) (5-b)(4-6-62)= -64(5-b)= -320+64b= 64b-320.

Answer 2

It seems like you've provided two expressions:

1. $(2 - a)(16 - a + a^2)$
2. $(5 - b)(4 - 6 - 62)$

Let's simplify each expression:

1. $(2 - a)(16 - a + a^2)$ To simplify this expression, you can use the distributive property (FOIL method):

   First, multiply the first terms: $2 \cdot 16 = 32$ Outer terms: $2 \cdot (-a) = -2a$ Inner terms: $(-a) \cdot (16) = -16a$ Last terms: $(-a) \cdot (-a) = a^2$

   Now, combine all the terms: $32 - 2a - 16a + a^2$ Combine like terms: $32 - 18a + a^2$

   So, the simplified expression is $a^2 - 18a + 32$.

2. $(5 - b)(4 - 6 - 62)$ First, simplify the numbers: $4 - 6 - 62 = -64$

   Now, multiply the terms using the distributive property:

   First terms: $5 \cdot -64 = -320$ Outer terms: $5 \cdot (-b) = -5b$ Inner terms: $(-b) \cdot (-64) = 64b$ Last terms: $(-b) \cdot (-b) = b^2$

   Combine all the terms: $-320 - 5b + 64b + b^2$ Combine like terms: $b^2 + 59b - 320$

   So, the simplified expression is $b^2 + 59b - 320$.
