r2+6r-7 = (r+7)(r-1) when factored
r2+r2 = 2r2
The LCM is r^3 + 9r^2 - 25r - 225.
The quadratic expression: r2+10r+25 = (r+5)(r+5) when factorised
r+2
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
(r + 2)(r + 2)
r -31
r(r + 5)
(r + 9)(r + 3)
r2 - 19r + 120 has no real factors.
