CAn you help me on how to solve polynomials

5 answers

there are many topics involved.
what particular problem is bothering you?
Just to start, google can provide you with many examples and solutions.
Always the best place to start on a general question like this.
(m^2 - m - 3) + (m - 4)

f^2 x f^4

Simplify the expression
-x(7x - 8)
(m^2 - m - 3) + (m - 4)
m^2 - m - 3 + m - 4 = m^2 -m+m -3-4 = m^2 + 0 -7 = m^2-7

f^2 x f^4 = f^(2+4) = f^6

Simplify the expression
-x(7x - 8) = -7 x^2 + 8 x
