x2 = -11x - 10
x2 + 11x + 10 = 0
(x + 1)(x + 10) = 0
The factors of x2 are x and x.
x2 - 5x + 6 = (x - 2)(x - 3)
x2+9x-36 = (x-3)(x+12) when factored
If you mean x2+11x+24 then it is (x+3)(x+8) when factored
The factor pairs of 111 are 1x111, 11x10. These are in order.
You take 11x10 then by 2...
Well, darling, 11 times 10 equals 110. It's basic math, not rocket science. So, there you have it. Math lesson complete.
If: x2 = 81 Then: x = 9 or x = -9
X squared equals x times x.
do you mean x2 + 3x + 2 ? Factors are (x +2)(x+1)
(x + 8)(x + 2)
x2 + x2 = 2x2
(20+5) + (11x10) -14
x2 - 42x + 441 = (x - 21)2
x1:y1 = x2:y2 4:-2 = x2:5 x2 = (4*5)/-2 x2 = -10
110
The given expression does not have rational factors, so the question cannot be abut factorising. Evaluating x2 - 14x + 9 depends on the value of x.
