(a-d)/2c=b
b-squared plus 5b plus 1 is an expression: not an equation or inequality. There is, therefore, nothing that can be solved. Second, the expression does not have real factors. It makes no sense to use product (factor) and sum to find complex factors. Using the quadratic formula or completing the squares are far simpler.
d=a-2bc
Gathering like terms together, this can be rewritten: 9a = 180 Dividing both sides of the equation by 9: a = 20
Triangles or squares or hexagons. There are also mixtures, like octagons plus squares.
It cannot be, unless you use extremely complicated fractions.
Using the communative property of both addition and multiplication, 11+ab could be rewritten as ab+11, 11+ba or ba+11.
That expression can't actually be factored without using complex numbers. If you want to use complex numbers, then it would come out as a "difference of squares":(x + i)(x - i)

Plus 12 plus -13 plus plus 1 can be rewritten in mathematical terms as: 12+(-13)+1 or 12-13+1 12-13+1 =-1+1 =0
c= a-2b
a-2b=c
d=a-2bc
c = 12.25
U turn a square into four squares by making a plus sign
There is a formula for the difference of two squares. The sum of two squares doesn't factor.
