Answer 1

$\huge{\underline{\sf{\red{Answer}}}}$

$\huge \implies \large \sf \: d \: = {b}^{2} - 4ac$

$\implies \large \sf \: b \: = 5 \\ \implies \large \sf \: a = 1 \: and \: c = 10 \\ \\ \huge\bold \green{Now,} \\ \implies \large \sf \: d = {5}^{2} - 4(1)(10) \\ \implies \large \sf \: d = 25 - 40 \\ \implies \large \sf \: d = - 15 \\ \\ \implies \large \sf \red{if \: roots \: are \: negative \: then \: } \\ \sf\red {there \: are \: no \: real \: roots}$

Answer 2

Answer

⟹b=5

⟹a=1andc=10

Now,

⟹d=5

2

−4(1)(10)

⟹d=25−40

⟹d=−15
