What are the zeros of g(x)=x(x^2-25)(x^2-3x-4)

denis-greek [22]

Answer:

$\large\boxed{x\in\{-5,\ -1,\ 0,\ 4,\ 5\}}$

Step-by-step explanation:

The zeros of g(x):

$g(x)=x(x^2-25)(x^2-3x-4)\to g(x)=0\\\\x(x^2-25)(x^2-3x-4)=0\iff x=0\ \vee\ x^2-25=0\ \vee\ x^2-3x-4\\\\x^2-25=0\qquad\text{add 25 to both sides}\\x^2=25\to x=\pm\sqrt{25}\\x=-5\ \vee\ x=5\\\\x^2-3x-4=0\\x^2+x-4x-4=0\\x(x+1)-4(x+1)=0\\(x+1)(x-4)=0\iff x+1=0\ \vee\ x-4=0\\x=-1\ \vee\ x=4$

IM LITERALLY BEGGIIINNGG HURRRYYYY PLSSSS HELP MEH

Dmitrij [34]

x is 53

angle PQD is equal to APQ. so its 62 degrees

PRC and PRD are supplement so their sum is 180.

PRD=115 PRC= 180 -115= 65

the sum of the angles of a triangle is equal to 180. so:

$x = 180 - (62 + 65) = 53$
