-8x+24 {This answer may be wrong: I think the question was intended to read, "Factor x2 - 10x + 24?" If so, the factors are (x - 6) and (x - 4)}

For a start you tell us what the expression equals....

x2 + 10x + 21 = (x + 3)(x + 7)

(x2+10x+21)/(x+3) = (x+7)

x2 - 10x - 24= x2 - 12x + 2x - 24= x(x - 12) + 2(x - 12)= (x - 12)(x + 2)

x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10

X2 + 8x + 16 = 10x +16x2 + 8x + 16=2x + 8x + 16=10x + 16

depends on what x is

x2 + 9 = 10x x2 - 10x + 9 = 0. (x - 9)(x - 1) = 0. Therefore, x = 1 or 9.

x2+10x+21 = (x+3)(x+7)

x2+10x+1 = -12+2x x2+10x-2x+1+12 = 0 x2+8x+13 = 0 Solving by using the quadratic equation formula: x = - 4 - or + the square root of 3

That expression can not be factored.

Twenty-Five x2 + 10x = 8 x2 + 10x + 25 = 8 + 25 (x + 5)2 = 33

x2-10x-24 = (x+2)(x-12) when factored

(x + 8)(x + 2)

x = -3.27 or -6.73

(x + 2)(x - 12)

25

x2 - 10x + 25 = 0(x - 5)(x - 5) = 0x - 5 = 0x = 5

x2+10x+1 = -12+2x x2+8x+13 = 0 The solution: x = -4 + the square root of 3 or x = -4 - the square root of 3

(x+1)(x+9)
