Answer:
8
Step-by-step explanation:
The condition for the discriminant b² - 4ac is
If b² - 4ac > 0 then roots are real, irrational and unequal
If b² - 4ac > 0 and a perfect square, roots are real, rational and unequal.
Thus
b² - 4ac = 8
Answer:
3) 8
Step-by-step explanation:
Real and unequal:
B² - 4AC > 0
Irrational: B²-4AC not a perfect square
Answer:
2(2x + 4) – 3(x - 1) = 11
4x+8-3x+3=11
4x-3x+8+3=11
x+11=11
x=0
Step-by-step explanation:
Answer:
x = 0
Step-by-step explanation:
Given
2(2x + 4) - 3(x - 1) = 11 ← distribute parenthesis and simplify left side
4x + 8 - 3x + 3 = 11
x + 11 = 11 ( subtract 11 from both sides )
x = 0
