Felicity Whitehead · Answer 1

Ax² + bx + c = 0

2x² + x - 3 = 0

2x² + x + (-3) = 0

x = - b + / - √b² - 4ac

2a

x = 1 + / - √1² - 4 (2) (-3)

2 (2)

x = 1 + / - √1 + 24

4

x = 1 + / - √25

4

x = 1 + / - 5

4

x = 1 + 5 x = 1 - 5

4 4

x = 6 x = - 4

4 4

x = 3 x = - 1

2

x = 1 1/2

x = 1 1/2 x = - 1
