which part of the qu solved through factorizingadratic formula tells whether it can be

Answer 1

You can factor the \(\large\color{blue}{ \rm ax^2+bx+c }\) if

\(\large\color{blue}{ \rm b^2-4(a)(c)}\) (the discriminant) is a perfect square.

Answer 2

thnx

Answer 3

plz solve for x in 16x squared -81=0

Answer 4

\(\large\color{blue}{ \rm 16x^2-81=0 }\)

\(\large\color{blue}{ \rm 16x^2=81 }\)

\(\large\color{blue}{ \rm 16x^2=9^2 }\)

\(\large\color{blue}{ \rm 4^2x^2=9^2 }\)

\(\large\color{blue}{ \rm (4x)^2=9^2 }\)

\(\large\color{blue}{ \rm 4x=± 9 }\)

\(\large\color{blue}{ \rm x=± 9/4 }\)

Answer 5

i think you are a genius...thnx

Answer 6
