The value of X in the equation 2x plus 36 = 4 is -16.
If: -8x+4 = 36 then the value of x works out as -4 Check: -8*(-4)+4 = 36
x2 + 13x + 36 = (x + 9)(x + 4)
(x + 4)(x + 9)
x2 + 13x + 36 = 0 so (x+4)(x+9) = 0 so that x = -4 or x = -9
5
(x + 9)(x + 4)
x - 4. x^2 + 5x - 36 = (x - 4) (x + 9) x^2 - 9x + 20 = (x - 4) (x - 5)
x/6 = 6 and 4/6 x = 36 plus 24/6 x = 36 plus 4 x = 40
(x+9)(x+4)
It is: (x-4)(x+9)
x2-13x+36=(x-9)(x-4)=0 x=9 or x=4
