Step-by-step explanation: Took the test.

Answer 2

X1=0+40/8=5(A)

X2=0-40/8=-5(B)

RTA= 5 and -5 are the roots of the equation

Explanation:

F(x)=4X^2-100=0

You do BHASKARA in order to get the roots(or zeros)

0(√0-4·4·-100)/2·4=

X1=0+40/8=5(A)

X2=0-40/8=-5(B)

RTA= 5 and -5 are the roots of the equation
