Use the distributive property to factor the GCF for the following expressions.
a. 8x^3 − 30x b. -2a^2 + 4x + 10 c. 7wx^2 − wx
a. HCF = 2x.
\(8x^3 - 30x = 2x(4x^3 - 15)\)
b. HCF = 2
\(-2a^2 + 4x + 10 = 2(-a^2 + 2x + 5)\)
c. HCF = wx
\(7wx^2 - wx = wx(7x - 1)\)
just to clarify: HCF = Highest Common Factor?
Yes.
