Answer:

Multiply both terms of the numbers

hense you would do: 2(9a + 12) = 18a + 24

It doesn't have to be 2 however. If can be any number you want it to be

4x squared + 29x + 30=0

saveliy_v [14]

So for this equation we're going to complete the square.

Firstly, what two terms have a product of 120x^2 and a sum of 29x? 24x and 5x. Replace 29x with 24x + 5x: $4x^2+24x+5x+30=0$

Next, factor 4x^2 + 24x and 5x + 30 separately. Make sure that they have the same quantity inside the parentheses: $4x(x+6)+5(x+6)=0$

Now you can rewrite the equation as: $(4x+5)(x+6)=0$

Now using zero product property, solve for x:

$4x+5=0\\ 4x=-5\\ x=-1.25\\ \\ x+6=0\\ x=-6$

In short, x = -1.25 and -6

Perform the indicated operation. <br> f(x) = x^3 + 5x<br> g(x) = 4x<br> Find (f . g)(x)

cestrela7 [59]

Step-by-step explanation:

$f(x) = {x}^{3} + 5x \\ g(x) = 4x \\ \\ \therefore \: (f.g)(x) = f(x) . g(x) \\ = ( {x}^{3} + 5x ).4x \\ = {x}^{3} .4x + 5x.4x \\ \red{{ \boxed{\bold{\therefore \: (f.g)(x) = 4 {x}^{4} + 20 {x}^{2} }}}}$
