Question

Identify all of the root(s) of g(x) = (x2 + 3x - 4)(x2 - 4x + 29)

Answer 1

The answer above is correct:

B. 1

C. 4

E. 2+5i

F. 2-5i

Explanation:

I got this right on Edg. 2021

Answer 2

x=-4,1,2+5i,2-5i

Explanation:

Given is an algebraic expression g(x) as product of two functions.

Hence solutions will be the combined solutions of two quadratic products

`g(x) = (x^2 + 3x - 4)(x^2 - 4x + 29)\\`

I expression can be factorised as

`(x+4)(x-1)`

Hence one set of solutions are

x=-4,1

Next quadratic we cannot factorize

and hence use formulae

`x=(4+/-√(16-116) )/(2) =2+5i, 2-5i`
