x2 - 13x = 0x (x - 13) = 0x = 0andx = 13
2x2 + 13x - 7 = zero(2x - 1 )( x + 7 ) = zero2x - 1 = zerox = 1/2x + 7 = zerox = -7
Let square = [x] -4+3*(-2)*[-4]+[3x-2x]=-4-6-2+[x]=-12+[x]The answer is negative 12 plus squared x.
x2 + 13x + 40 = x2 + 5x + 8x + 40 = x(x + 5) + 8(x + 5) = (x + 8)(x + 5)
x2 + 13x + 36 = 0 so (x+4)(x+9) = 0 so that x = -4 or x = -9
It is x^2 -13x +12 = (x-1)(x-12) when factored
x2 + 13x + 12 = (x + 1)(x + 12)
It is (x+6)(x+7) when factored
42 + x2 = 13x ∴ x2 - 13x + 42 = 0 ∴ (x - 6)(x - 7) = 0 ∴ x ∈ {6, 7}
It is: (x+1)(x+12) when factored

x represents an unknown number.
2x+x+x+9x+2+12 - add the like terms =13x+14 13x and 14 cannot be added because they aren't like terms.
(x - 3)(2x - 7)
x^2 + 13x + 30 = 0 x^2 + 10x + 3x + 30 = 0 x(x + 10) + 3(x + 10) = 0 (x + 3)(x + 10) = 0 x = -3 or x = -10
It is (2x-5)(x-4) when factored
