Question

Term

c2 + 10c - 25 = 0

a2 - 5a - 14 = 0

16y2 - 8y + 1 = 0

5x2 + 8x + 16 = 0

Definition

A) 1 real (rational)

B) 2 complex (conjugate)

C) 2 rational roots

D) 2 irrational roots

Answer 1

Each of the equations (what you call term(?)) is a quadratic.  Why don't you solve them, using factoring, or the quadratic formula, or completing the square, or whatever method you use to solve quadratics.  Then decide what kind of solution(s) you have.  Then you will have the answers.  Not before!

Answer 2

16y2 - 8y + 1 = 0 : A

5x2 + 8x + 16 = 0 : B

a2 - 5a - 14 = 0 : C

c2 + 10c - 25 = 0 : D

Answer 3

16y2 - 8y + 1 = 0 :  A

5x2 + 8x + 16 = 0  : B

a2 - 5a - 14 = 0  : C

c2 + 10c - 25 = 0  : D

Answer 4

1 real

2 rational roots

3. irrational roots

4. complex
