(X+5)(X+6)

x2 + 11x + 30 = 0 (x + 5)(x + 6) = 0 so the roots are -5 and -6

The factors of (x2 + 11x + 30) are (X + 5) and (x + 6)You want to look for two numbers, when multiplied equal 30, and when added equal 11. Start with factors of 30, and see what they add to: 5+6=11, and 5*6=30.

There's a factor pair of 30 that adds up to 11. (x + 5)(x + 6)

The actual equation itself is the polynomial. There is no polynomial for it, and your question doesn't really make sense.

(x+5)(x+6) equals x^2 +11x+30

66x^3 - 36x^2 = 6x^2(11x - 6) 55x - 30 = 5(11x - 6) 66x^3 - 36x^2 + 55x - 30 = (6x^2 + 5)(11x - 6)

the answer is 300

It depends on what x is... You have to have either an x value or an answer to the equation. If x is 1, then it's 42. If x is 2, then it's 56.

-x^2 - 11x - 30 If you intended -1(x squared), making a quadratic equation, the solutions are -1 and +6.

x/6 + x/5 = 11 Multiply throughout by 30: 5x + 6x = 330 => 11x = 330 => x = 30

300

-(x + 5)(x + 6)

if f(x) = x3 + 4x2 - 11x - 30, then yes, (x - 3) is indeed a factor. f(x) = x3 + 4x2 - 11x - 30 ∴ f(x) = (x - 3)(x2 + 7x + 10) ∴ f(x) = (x - 3)(x + 2)(x + 5)

30 + 30 + 30 + 30 + 30 + 30 = 180

50 + 40 + 40 + 40 + 30 + 30 + 20 + 10 = 260

-30 plus 60 = 30

The sum of these numbers is 563.

40 + 57 + 40 + 30 + 47 + 31 + 60 + 38 + 64 + 30 + 120 = 557
