Which shows the factored form of x2 – 12x – 45? (x 3)(x – 15) (x – 3)(x – 15) (x 3)(x 15) (x – 3)(x 15).
Aleksandr [31]

The factors of the quadratic equation are (x+3) and (x-15).

<h2 /><h2>Given to us</h2>
  • x^2-12x-45\\

<h3>To find</h3>

The factors of x^2-12x-45\\.

<h3 /><h3>Solution</h3>

x^2-12x-45\\

As we can see in the quadratic equation the value of ac is -45x². therefore, we need to divide -12x into two parts such that their sum must give -12x and their product gives us -45x².

therefore, dividing -12x into -15x and 3x,

x^2-15x+3x-45\\

Taking common out,

x^2-15x+3x-45\\x(x-15)+3(x-15)\\(x+3)(x-15)

Hence, the factors of the quadratic equation are (x+3) and (x-15).

vredina [299]

Answer:Magnitude of voltage is 41.9963 volts


Step-by-step explanation:

Given that current I =5.772-5.323i mA

          and impedance, Z=3.342+4.176i kilo ohms

Then voltage in the circuit = IZ

                                            =(5.772-5.323i)X10^{-3}X(3.342+4.176i)X10^{3}

                                      V=(5.772-5.323i)X(3.342+4.176i)

                                      V=19.290024+24.103872i-17.789466i-23..5148848i^{2}

                                     V=41.518892+6.314406i

Magnitude of V = \sqrt{41.518892^{2} +6.314406^{2} }=\sqrt{1763.6901}=41.9963volts
