Use the distributive property. For the first set of parenthesis, multiply everything inside by 8. This gets you to 8x-8.
Next set: Everything inside by 3x: 12x+3x^2.
Next set: Everything inside by 6: 6x+12.
Put it all together: 8x-8-12x+3x^2+6x+12-3.
Combine like terms: 2x+1+3x^2
Answer:
1 and -1
Step-by-step explanation:
Factoringfind a number set that equals zero and when multiplyed, becomes -1.
1 and -1 multiply to -1 and equal 0,
so x^2-1 turns into (x+1)(x-1)
solve for both x+1=0 and x-1=0
x+1=0
x=-1
x-1=0
x=1
