Answer:
-85m, -2.4m, 0m, 88m, and 1,011m
Step-by-step explanation:
Easier if you first factor out the " - " sign. Then you have:
–8x3 – 2x2 – 12x – 3 = -1(<span>8x3 + 2x2 + 12x +3).
</span>
Start with 12 + 3. This factors to 3(4x+1). Next, focus on 8x^3+2x^2. This factors to 2x^2*(4x+1). So, the binomial factor 4x+1 is common to the first two terms and the second two terms. We get: (4x+1) ( 2x^2 + 3).
Now put the "-" sign back in, and we get - (4x+1) ( 2x^2 + 3) (answer)
Please note: Use "^" to denote exponentiation. 2x2 is meaningless; it should be 2x^2.
Answer:
Step-by-step explanation:
Rewrite this quadratic in standard form: 3x^2 + 7x - 1.
The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or
7^2 - 4(3)(-1), or 49 + 12, or 61. Because the discriminant is positive, this quadratic has two real, unequal roots
