If (x+1) is a factor of x^3+2x^2-x-2, find the remaining factors.
Alexxandr [17]
Using synthetic division to divide x³ + 2x² - x - 2.  Since (x + 1) is the factor, we can divide by -1.  See the attached file for the synthetic division.  After that, we are left with x² + x - 2.  This can easily be factored into (x + 2)(x - 1).  The remaining factors are (x + 2) and (x - 1).

If tn is 2n+3 find t7 t30 and s10​
Andreas93 [3]

Answer:  t₇ = 17     t₃₀ = 63       S₁₀ = 140

<u>Step-by-step explanation:</u>

t₇ = 2(7) + 3

  = 14 + 3

  = 17

t₃₀ = 2(30) + 3

    = 60 + 3

    = 63

S₁₀ = (t₁ + t₁₀)/2 × 10

    = (5 + 23)/2 × 10

    = 28/2  10

    = 14 × 10

    = 140
