If the 64 has a minus sign, then the solution is x = +/-5 Simplifying gives 4x squared = 100 ie x squared = 25...
x sq equalls 36 and x equalls plus or minus 6
(x^2 - 4)(x^2 + 9) set to zero to see roots ( watch out for the surprise! )
62 = 36
x^2 - 13x + 36 = 0 Factor: (X-9)(X-4) = 0 X = 9 X = 4
x = plus or minus 6.
a2 + 62 = 122 a2 + 62 - 62 = 122 - 62 a2 = 144 - 36 a2 = 108 taking the square root of each side, we get a equal plus or minus the square root of 108, or plus or minus 6 times the square root of 3.
36+4=40 40-8=32 32-25 equals=7 answer
If the 64 has a minus sign, then the solution is x = +/-5 Simplifying gives 4x squared = 100 ie x squared = 25...
(x + 12)(x - 3)
0 = 2m^2 - 2m + 36 0 = 2(m^2 - m + 18) 0 = m^2 - m + 18
The graph is a circle with a radius of 6, centered at the origin.
x = ±2
x sq equalls 36 and x equalls plus or minus 6
