x2-5x-36 = (x-9)(x+4) when factored
x sq equalls 36 and x equalls plus or minus 6
9x2 + 27x - 36 = 9(x2 + 3x - 4) = 9(x + 4)(x - 1)
964 = 1,000 - 36
(5y - 6)(5y + 6)
x2-5x-36 = (x-9)(x+4) when factored
(x + 6)(x - 6)
4(y - 3)(y + 3)
(x + 12)(x - 3)
(6x - 1)(6x - 1)
49x2 - 84x + 36 = (7x - 6)(7x - 6) or (7x - 6)2
x sq equalls 36 and x equalls plus or minus 6
9x2 + 27x - 36 = 9(x2 + 3x - 4) = 9(x + 4)(x - 1)
x 2 - 5x - 36 = 0; factor. (x-9)(x+4) = 0; set each factor = 0. x - 9 = 0 and x + 4 = 0 So, x = 9 and x = -4.
964 = 1,000 - 36
0.4822530864
x = plus or minus 6.
