Standard form (b^2+5)(−b^2+7) polynomial is = -b⁴+2b²+35

What are polynomials?

  • A polynomial expression is an expression that can be built from constants and symbols.
  • Polynomials are algebraic expressions that comprise exponents which can be added, subtracted, or multiplied.
  • Polynomials are of different types.
  • Monomial- Linear equations (A monomial is a polynomial with one term)
  • Binomia l- quadratic equation (A binomial is a polynomial with two, unlike terms).

Using FOIL METHOD to expand.

(b²+5)(−b²+7)

=(b²+5)(7-b²)

=7b²-b⁴+35-5b²

=2b²-b⁴+35

= -b⁴+2b²+35
