12x = 4(x+5)
3x = x+5 divide by 4
2x = 5 subtract x
x = 2.5 divide by 2

If you mean (5x+3)2 = 36... 5x+3 must equal 6 so - 5x has to equal 3 - therefore x = 0.6
If you mean: y = 3(-3/2)2+9(-3/2)-8 Then: y = -59/4 or as -14.75
35
(x+8)(x-1)=0 x+8=0 x=-8 x-1=0 x=1 Therefore, the zeroes are -8 and 1.
X equals 2 :)
