I guess that should be 3 times (x squared) minus 48: 3x2 - 48 = 3(x2 - 16) = 3(x + 4)(x - 4)
-3x2 + 16x + 12 = -3x2 + 18x - 2x + 12 = -3x*(x - 6) - 2(x - 6) = -(3x + 2)*(x - 6)
No.

With difficulty because it's not an equation but an expression.
3x2 + 48 + 192 = 3x2 + 240 = 3 (x2+ 80)
It is 4 terms of an algebraic expression.
3x2-24x-48 is not factorable.
(3x-12)(x-4)
That's 35 - 30x. The GCF of 35 and 30x is 5.
3x2 + 27x +60
x = 0.666666666666667 so 100 + (30x0.67) + (30x0.67) = around 180

3x2=6+38=44
3x2+26x+16 When factorised: (3x+2)(x+8)
