r^2 - 12r + 27 what two factors of 27 add up to - 12? (r - 3)(r - 9) FOIL that and get the quadratic polynomial back
r(r + 5)
(r + 2)(r + 2)
(pi*r2)/2 + 4000
r2+6r-7 = (r+7)(r-1) when factored
r^2 - 12r + 27 what two factors of 27 add up to - 12? (r - 3)(r - 9) FOIL that and get the quadratic polynomial back
r(r + 5)
(r + 2)(r + 2)
2 squared is 4 3 cubed is 27 27 plus 4 is 31
27
r2+r2 = 2r2
The quadratic expression: r2+10r+25 = (r+5)(r+5) when factorised
The LCM is r^3 + 9r^2 - 25r - 225.
multiply r2+7r+10/3 by 3r-30/r2-5r-50 weegy
r1 plus r2 is the measurement of the combined electrical continuity of the phase conductor and circuit protective conductor on and electrical circuit.
It could be lots of things. One answer can be: r2 + 9 = r2 + 32.
(pi*r2)/2 + 4000
