Answer:

Given f(x) = x2 + 3x – 1, find

a) f(1)

b) f(–1)

c) f(a)

d) f(x – 1)

Step-by-step explanation:

a) f(1) = (1)2 + 3(1) – 1 = 3

b) f(–1) = (–1)2 + 3(–1) – 1 = –3

c) f(a) = a2 + 3a – 1

d) f(x – 1) = (x – 1)2 + 3(x – 1) – 1

= x2 – 2x + 1 + 3x – 3 – 1 = x2 + x –3

Factor this expression completely.<br><br> u^3 - v^3

Musya8 [376]

Completely factored form of u^3-v^3 is:

$(u-v)(u^2+uv+v^2)$

Step-by-step explanation:

Algebraic formulas are used to factorize the expression.

Given

$u^3 - v^3$

The formula involving cube with negative sign is:

$a^3-b^3 = (a-b)(a^2+ab+b^2)$

Using this formula:

$u^3-v^3 = (u)^3 - (v)^3\\= (u-v)(u^2+uv+v^2)$

Hence,

Completely factored form of u^3-v^3 is:

$(u-v)(u^2+uv+v^2)$
