Answer:

33x + 3

Step-by-step explanation:

To expand an equation like the one you have shown, multiply the 3 with everything inside the parenthesis.

3*11x=33x

3*1=3

Answer: 484

===============================================

Work Shown:

First let's compute f(2). We replace every x with 2 and then use PEMDAS to simplify

f(x) = -x^4 + 5x - 4x^2

f(2) = -(2)^4 + 5(2) - 4(2)^2

f(2) = -16 + 5(2) - 4(4)

f(2) = -16 + 10 - 16

f(2) = -6 - 16

f(2) = -22

Then we square this result to find the value of $[ f(2) ]^2$

$f(2) = -22\\\\\left[ f(2) \right]^2 = [ -22 ]^2\\\\\left[ f(2) \right]^2 = 484$

(3x-4y)^2-(3x-4y)(3x+4y)

zheka24 [161]

Answer:

$-24xy + 32y^2$

Step-by-step explanation:

Hello!

We can use the special binomial product formulas:

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

<h3>Simplify</h3>

$(3x - 4y)^2 - (3x - 4y)(3x + 4y)$
$(9x^2-24xy+16y^2) - (9x^2 - 16y^2)$
$9x^2 - 9x^2 - 24xy + 16y^2 + 16y^2$
$-24xy + 32y^2$

The simplified form is $-24xy + 32y^2$
