Calculate the discriminant: 5x² + 2x − 2 = 0

44

Step-by-step explanation:

The equation is of the form  a x ²+bx +c = 0 where

a = 5, b= -2, c= -2

The Discriminant is given by:

Δ= b²− 4  * a  *  c

=  (−2²)−  ( 4  *  5  *  ( −  2 ) )

=  4 +  40

= 44

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
