Ответ:
Объяснение:
можно решить используя теорему Виета:
при \left \{ {{c=-4*(-14)} \atop {b=-(-4+(-14))}} \right. <=> \left \{ {{c=56} \atop {b=-(-4-14)}} \right. <=> \left \{ {{c=56} \atop {b=-(-18)}} \right. <=> \left \{ {{b=18} \atop {c=56}} \right." alt="a=1, \left \{ {{x_1x_2=c} \atop {x_1+x_2=-b}} \right. <=> \left \{ {{c=-4*(-14)} \atop {b=-(-4+(-14))}} \right. <=> \left \{ {{c=56} \atop {b=-(-4-14)}} \right. <=> \left \{ {{c=56} \atop {b=-(-18)}} \right. <=> \left \{ {{b=18} \atop {c=56}} \right." align="absmiddle" class="latex-formula">
