Answer:
2.Let's solve your equation step-by-step.
x3+3x2+3x+1=0
Step 1: Factor left side of equation.
(x+1)(x+1)(x+1)=0
Step 2: Set factors equal to 0.
x+1=0 or x+1=0 or x+1=0
x=−1 or x=−1 or x=−1
Answer:
x=−1 or x=−1 or x=−1
3.Let's solve your equation step-by-step.
x3+5x2+xx−48=0
x3+6x2−48=0
Step 1: Use cubic formula.
x=2.391647
Answer:
x=2.391647
4.Let's solve your equation step-by-step.
x3+10x2+17x=28
Step 1: Subtract 28 from both sides.
x3+10x2+17x−28=28−28
x3+10x2+17x−28=0
Step 2: Factor left side of equation.
(x−1)(x+4)(x+7)=0
Step 3: Set factors equal to 0.
x−1=0 or x+4=0 or x+7=0
x=1 or x=−4 or x=−7
Answer:
x=1 or x=−4 or x=−7
Step-by-step explanation:
Sorry po hindi ko po masagutan yung number 1 ang hirap po kasi
