Question

Factor x^2 – 7x + 10, 4x^2 – 81 and p (x) = 3x^3 – 12x

Answer 1

This is one of the way to show ur eqn is right...

Answer 2

ur quadractic expression*

Answer 3

\((x-5)(x-2)\)

Answer 4

u can also double check ur quadractic expression by opening the bracket...
\(\color{red}{(}x-5\color{red}{)}\color{red}{(}x-2\color{red}{)}\)

Answer 5

this quadractic expression is a bit special...

Answer 6

\(4x^{2}-81\)

Answer 7

to factor that expression u will need to use this formula which is

Answer 8

\(a^2-b^2=(a\color{red}{-}b)(a\color{red}{+}b)\)

Answer 9

let's see...
\(\color{red}{4}x^{2}-\color{red}{81}\)

Answer 10

we could try an exponent of 2...

Answer 11

\(2^{2}x^{2}-9^{2}\)

Answer 12

\(2^\color{red}{2}x^\color{red}{2}-9^\color{red}{2}\)

Answer 13

since,all has the same exponent,it will be easier for us to factor that quadractic expression by using the formula \(a^{2}-b^{2}=(a-b)(a+b)\)
