please help me with my Homework question 6 a and 6b

t 6 Les 3 Probs 5-7.pdf
6. Each of the following trinomials has a non-prime leading coefficient. Using a guess-and-check technique,
write each trinomial in its factored form. Show each guess and its check.
(a) 18x' – 25x+8
(b) 20.x – 1 Lx –42
REASONING
7. Consider the trinomial 12x² + 7x–10.
(b) Why is (4x-2)(3x+5} not an intelligent
(a) Does this trinomial have a greatest common
factor that could bo “factored out"?
guess for factoring this trinomial even though
4.3 =12 and -2-5=-10? Consider your
answer to part (a).
