Answer:

<u>5x³ + 30x² + 45x = 5x (x+3)²</u>

Step-by-step explanation:

Given: 5x³ + 30x² + 45x

Take 5x as a common

5x³ + 30x² + 45x

= 5x ( x² + 6x + 9) ⇒ Factor ( x² + 6x + 9)

= 5x (x+3) (x+3)

= <u>5x (x+3)²</u>

Ariana plans to use $260 less than three-fourths of savings to buy a car. If the purchase price of the car is 9,340, how much do
tangare [24]

She has $12,488 in savings

Step-by-step explanation:

Ariana plans to use $260 less than three-fourths of savings to buy a car.

If the purchase price of the car is 9,340, we need to find how much

she has in savings

To find the savings

  • Assume that she has $x in savings
  • Write an equation of x
  • Solve the equation to find x

∵ She has $x in savings

∵ She plans to use $260 less than three-fourths of savings

- Three-fourths means \frac{3}{4} and less than means subtract

∴ She plans to use \frac{3}{4} x - 26

∵ The purchase price of the car is 9,340

- Equate the expression of x by 9,340

∴ \frac{3}{4} x - 26 = 9,340

Now let us solve the equation

∵ \frac{3}{4} x - 26 = 9,340

- Add 26 to both sides

∴ \frac{3}{4} x = 9,366

- Divide both sides by \frac{3}{4}

∴ x = $12,488

She has $12,488 in savings

Find a degree 3 polynomial with real coefficients having zeros 1 and 2-2i and a lead coefficient of 1. Write P in expanded form.
amm1812

Answer:

Step-by-step explanation:

complex roots always occur in pairs.

roots are 1,2-2i,2+2i

P(x)=a(x-a)(x-b)(x-c)

P(x)=1(x-1)[x-(2-2i)][x-(2+2i)]

=1(x-1)[(x-2)+2i][(x-2)-2i]

=(x-1)[(x-2)²-(2i)²]

=(x-1)[(x-2)²-4i²]

=(x-1)[x²-4x+4-4(-1)]

=(x-1)[x²-4x+4+4]

=(x-1)[x²-4x+8]

=x³-4x²+8x-x²+4x-8

=x³-5x²+12x-8
