Question

Given the trinomial 5x2 - 2x - 3, predict the type of solutions.

Two rational solutions

One rational solution

Two irrational solutions

Two complex solutions

Answer 1

Descates rule of signs
+ - -
yes no
one positive and one negative root

Answer 2

5x^2 -2x -3
(5x +3)(x-1)
x = -3/5; x = 1

Answer 3

ahhh ok i got it

Answer 4

the degree of the polynomial will also determine the number of roots

2nd degree 2 roots
3rd 3 roots
4th degree 4 roots etc

Answer 5

so its a

Answer 6

i agree

Answer 7

thx

Answer 8

you are welcome

Answer 9

u can also use discremenant

Answer 10

\(\tt b^2 - 4ac > 0 .... two ~~real ~~roots \\
b^2 - 4ac = 0 .... one ~~real ~~root \\
b^2 - 4ac < 0 .... two ~~complex~~ roots\)

Answer 11

yes you can also use the discriminant where a, band c are the coefficients of a quadratic equation
