Simplify the polynomials: 8a·20b^2–0.8b·4b^2–20ab·2b+b·3b^2–1

  8a·20b^2–0.8b·4b^2–20ab·2b+b·3b^2–1

  the simplified form

  8a·20b^2–0.8b·4b^2–20ab·2b+b·3b^2–1

  = b^3(-0.8·4 +3) +ab^2(8·20 -20·2) -1 . . . . . group like terms

  = -0.2b^3 +120ab^2 -1 . . . . . the simplified form

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
