The value of X in the equation 2x plus 36 = 4 is -16.
(x + 4)(x + 9)
x2 + 13x + 36 = 0 so (x+4)(x+9) = 0 so that x = -4 or x = -9
x^(2) - 13x + 36 Factors to ( x - 9)(x - 4)
(x + 9)(x + 4)
5
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
odd one out is 43. The others are squares plus one. ie. 5 x 5 = 25 plus 1 = 26 6 x 6 = 36 plus 1 = 37 4 x 4 = 16 plus 1 = 17 9 x 9 = 81 plus 1 = 82 (solved verbally by Gary Timmins)
