Question

10th Std Maths part 1​

Answer 1

Answer:

Roots are 5 and -4

Sum of roots = 5+(-4) = 1

Product of roots = 5×(-4) = -20

We know that,

x²-(Sum of roots)x + (Product of roots)

x²-(1)x + (-20)

x² - x - 20

Hope it helps you

Answer 2

Step-by-step explanation:

$\mathfrak{ \large { \green { \underline{\underline{Given}}}}} \\ \large \red{roots \: of \: the \: polynomial \:are \: 5 \: and \: -4} \\ \mathfrak{ \large{ \blue{sum \: of \:the \: roots \: = \: 5 + ( - 4)}}} \\ \mathfrak{\large{\blue{ => \: 1}}} \\ \mathfrak{ \large{\blue{product \: of \: roots \: = \: 5 \times ( - 4)}}} \\ \mathfrak{ \large{ \blue{ => - 20}}} \\ \large \red{quadratic \: equation \: = \: {x}^{2} - (sum \: of \: roots)x \: + \: product \: of \: roots} \\ \large \orange{ quadratic \: equation \: = \: {x}^{2} - x - 20}$
