Factor.
-$$\mathrm { y } ^ { 2 } + 0.2 \mathrm { y } - 0.35$$
A) $( y - 0.7 ) ( y + 0.5 )$
B) $( \mathrm { y } + 0.7 ) ( \mathrm { y } - 0.5 )$
C) $( y + 0.1 ) ^ { 2 }$
D) $( \mathrm { y } - 0.7 ) ( \mathrm { y } - 0.5 )$

Question

Quizplus · Accepted Answer

The quadratic can be factored by finding two numbers that multiply to -0.35 and add to 0.2, which are 0.7 and -0.5. Thus, the factorization is $(y + 0.7)(y - 0.5)$.
