(x+9)(x+4)

Factors of 36 which add to 13 are 4 & 9 so: (x + 4)(x + 9) or (x - 4)(x - 9) depending on the sign of the term 13x.

The factors of x2-13x+36 are 'x-9' and 'x-4'because the expression (x-9)(x-4) can be simplified as x2-13x+36.

If that's plus 36, it factors to (x - 9)(x - 4) If it's minus 36, it gets ugly in a hurry.

x2-13x+36 = (x-4)(x-9) when factored

x2 + 13x + 36 = (x + 9)(x + 4)

Let your numbers be x and y So you can write the equations... x+y=13 and xy=36 Solving the first equation you get y=13-x Using substitution (plugging the equation above into the second equation) x(13-x)=36 13x - x^2 = 36 Set your equation equal to zero... x^2 - 13x + 36 = 0 Factoring... (x-9)(x-4)... so, x=9 and x=4 Plugging these values back into your original equations gives you that one of your answers is 9 and the other is 4.

Factors are things you multiply. In the equation 9 x 4 = 36, 9 and 4 are factors of 36.

6(13x + 6)

x2-13x+36=(x-9)(x-4)=0 x=9 or x=4

36 and 12

Two factors. 9 and 4 are factors of 36.

(x-4)

36 is composite because it has more than two factors. 1,2, 3, 4, 6,9 and 36 are the factors of 36.

x2 + 13x + 36 = 0 so (x+4)(x+9) = 0 so that x = -4 or x = -9

Factors go into numbers, numbers go into multiples. In the equation 9 x 4 = 36, 9 and 4 are factors of 36. 36 is a multiple of 9 and 4.

36. 6x6=36

Two and three.

The equation would be 35+36=71.

36 is a composite number because it has more than two factors whereas prime numbers have only two factors.

(x + 4)(x + 9)

(x - 9)(x - 4)

(x-4)(x-9)

(x + 9)(x + 4)
