Ajudaaaaaa

3º Escreva a equação ax 2 + bx + c = 0, quando:
a) a = 2, b = 4, c = 10 ________________________
b) a = 1, b = -1, c = 1 ________________________
c) a = 15, b = 20, c = 80 _______________________
d) a = 4, b = 0, c = 25 ________________________
e) a = -21, b = 7, c = 0 ________________________​

Answer 1

a) a = 2

b = 4

c = 10

2x² + 4x + 10 = 0

b) a = 1

b = - 1

c = 1

x² - x + 1 = 0

c) a = 15

b = 20

c = 80

15x² + 20x + 80 = 0

d) a = 4

b = 0

c = 25

4x² + 25 = 0

e) a = - 21

b = 7

c = 0

-21x² + 7x = 0
