It is still uncertain, from this writing whether 'x+3' is dividing just the '11X-19' aspect, or whether it is meant to be dividing all of the preceding. Normally, as it is written, it means the former: (a) Multiplication, in this problem, is done first, following the BODMAS rule: 2X3=6; 11X2=22; and 11X-19=-209 So, the problem now reads: 6+22+-209/(x+3) ANS = 28-209/(x+3) (b) If we assume the intended meaning is to divide the whole lot by x+3, in which case the original question should finish by saying, "all divided by x plus 3", the problem is set out such: [2X3+11X2+11X-19]/(x+3) = [6+22-209]/(x+3) =[28-209]/(x+3) ANS = 181/(x+3)
-4x2 + 11x - 6 factors to: (-4x + 3) (x - 2)
14 + 2x + 9x - 6 - 11x 14 - 6 + 2x + 9x - 11x The x values cancel themselves out, leaving just the number value The answer is therefore 8.
x2 + 11x + 30 = 0 (x + 5)(x + 6) = 0 so the roots are -5 and -6
It is: -4x^2 +11x -6 equals (-4x+3)(x-2) when factored
6 + 11x - 60 =6 - 60 + 11x = -54 + 11x = 11x -54

11x = 8x-6.............. 11x-8x = -6................... 3x= -6 x = -2
2x + 6 + 9x = 39 11x + 6 = 39 11x = 39 - 6 11x = 33 x = 3
x^2 + 11x + 6 has no rational zeros.
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
-4x2 + 11x - 6 factors to: (-4x + 3) (x - 2)
x+11x+30(x+5)(x+6)
14 + 2x + 9x - 6 - 11x 14 - 6 + 2x + 9x - 11x The x values cancel themselves out, leaving just the number value The answer is therefore 8.
Yes.
x2 + 11x + 30 = 0 (x + 5)(x + 6) = 0 so the roots are -5 and -6
It is: 11x -2 simplified
