Step-by-step explanation:

hello,

for the 1. you already posted a question

$25a^2-36b^2=(5a-6b)(5a+6b)\\$

$5x^{10}-80x^2 = 5x^2(x^{8}-16)$

as 16*5=80

let's go further

$5x^{10}-80x^2 = 5x^2(x^{8}-16)=5x^2((x^4)^2-4^2)=5x^2(x^4-4)(x^4+4)\\= 5x^2(x^2-2)(x^2+2)(x^4+4)$

Part A

f(x)=-16x^2+22x+3=-16x^2+24x -2x+3=8x(3-2x)+(3-2x)=(8x+1)(3-2x)

Part B f(x)=0 <=> 8x+1=0 or 3-2x=0 <=> x = -1/8 or x = 3/2

part C

$\lim_{x \to -\infty} f(x)=\lim_{x \to \infty} f(x)=-\infty$

because x^2 tends to $+\infty$ and then it is multiplied by -16

part D

we know that the graph is passing by (0,-1/8) and (0,3/2)

and we know the end behaviors from part C

please find below the graph

hope this helps

do not hesitate if you have any question
