Multiply it out.
  f(x) = (2x +1)(x² -1) . . . . . . recognize the factoring of the difference of squares

The standard form:
f(x)=ax^3+bx^2+cx+d
Use:(a-b)(a+b)=a^2-b^2\\\\(a+b)(c+d)=ab+ad+bc+bd\\\\a^n\cdot a^m=a^{n+m}
f(x)=(2x+1)(x+1)(x-1)\\\\f(x)=(2x+1)(x^2-1^2)\\\\f(x)=(2x+1)(x^2-1)\\\\f(x)=2x\cdot x^2-2x\cdot1+1\cdotx^2-1\cdot1\\\\f(x)=2x^3-2x+x^2-1\\\\\boxed{f(x)=2x^3+x^2-2x-1}

Whats (4.2×10^6)+(2.25 × 10^5) in scientific form
lys-0071 [83]
We are going to rewrite both numbers:
 (4.2 × 10 ^ 6) = 4200000
 (2.25 × 10 ^ 5) = 225000
 Adding we have:
 4200000 + 225000 = 4425000
 Rewriting in exponential notation we have:
 4425000 = 4,425 * 10 ^ 6
 Answer:
 
(4.2 × 10 ^ 6) + (2.25 × 10 ^ 5) is equal to:
 
4,425 * 10 ^ 6

jek_recluse [69]

Answer:

The margin of error is given below:

E=z \times \sqrt{\frac{\hat{p}(1-\hat{p}}{n} }

Where:

\hat{p}=\frac{26}{80}=0.325

\therefore E = z \times \sqrt{\frac{0.325(1-0.325}{80} }

                           =z \times 0.0523659

Therefore, the option E = z*6% is correct as it closest to the given answer
