3. Answer:
x=3/2+1/2√21 or x=3/2+-1/2√21
Step-by-step explanation:
For this equation: a=1, b=-3, c=-3
1x2+−3x+−3=0
Step 1: Use quadratic formula with a=1, b=-3, c=-3.
x=−b±√b^2−4ac/2a
x=−(−3)±√(−3)^2−4(1)(−3)/2(1)
x=3±√21/2
x=3/2+1/2√21 or x=3/2+−1/2√21
Answer:
3: x= 3.7912874, x= 0.79128784
4: x= 0.62181997, x= -4.28848664
Step-by-step explanation:
It’s all solve for x what number actually makes the equation true.
