if you mean  −10x^2 −7x+2=0  the answer is (d) a=−10; b=−7; c=2

$$\mathrm{if}\:\mathrm{you}\:\mathrm{mean} \\ $$$$−\mathrm{10}{x}^{\mathrm{2}} −\mathrm{7}{x}+\mathrm{2}=\mathrm{0} \\ $$$$\mathrm{the}\:\mathrm{answer}\:\mathrm{is}\:\left({d}\right)\:{a}=−\mathrm{10};\:{b}=−\mathrm{7};\:{c}=\mathrm{2} \\ $$
