The correct factorization of the trinomial [tex]-7x^{2} - 5x + 18[/tex] is Option (B) [tex]-1(7x - 9)(x + 2)[/tex]
How to factorize the given trinomial expression in the question ?
The given expression is - [tex]-7x^{2} - 5x + 18[/tex]
Factorizing the given expression -
= [tex]-7x^{2} - 5x + 18[/tex]
= [tex]-(7x^{2} + 5x - 18)[/tex]
= [tex]-(7x^{2} + 14x - 9x - 18)[/tex]
= [tex]-[7x(x + 2) - 9(x + 2)][/tex]
= [tex]-1(7x - 9)(x + 2)[/tex]
Thus the factorization of the equation is Option (B) [tex]-1(7x - 9)(x + 2)[/tex]
