Answer:

LAMBORGHINI

Step-by-step explanation:

The fact that Ferruccio Lamborghini first owned a Ferrari during his younger stage and it wasn't up to par for him still amazes me. He also had the guts to "repair" what was wrong with the Ferrari he had in his opinion and so Ferrari did not like that someone who at the time had a work related in the farms was telling him the imperfections that there was with a Ferrari since they were top tier luxury cars.

This is where the whole legacy that Ferruccio Lamborghini would leave behind started. He decided to switch fixing Ferraris as a hobby to making it a passion. Ever since Ferruccio's goal was to build a car that was equal or better than any Ferrari model at that time. People believed this was impossible!

In modern day standards both brands have continued to grow each making unique cars for different styles of people but If I had to chose one, It would be Lamborghini (Gallardo Super Trofeo) :)

Multiply. (2x2 + 4x - 3)(x2 - 2x + 5)

For a moment, let $y=x^2-2x+5$ . Then by the distributive property,

$(2x^2+4x-3)p=2x^2p+4xp-3p$

Again by the distributive property,

$2x^2p=2x^2(x^2-2x+5)=2x^4-4x^3+10x^2$

$4xp=4x(x^2-2x+5)=4x^3-8x^2+20x$

$-3p=-3(x^2-2x+5)=-3x^2+6x-15$

Taking everything together, we get

$(2x^2+4x-3)(x^2-2x+5)=(2x^4-4x^3+10x^2)+(4x^3-8x^2+20x)+(-3x^2+6x-15)$
$(2x^2+4x-3)(x^2-2x+5)=2x^4-x^2+26x-15$
