Question

the zeros of the polynomial 5 x square - 4 - 8 x is ​

Answer 1

$\tt \huge\underbrace {answer} \\ \\ \sf \: splitting \: the \: middle \: term \: \\ \\ \bf \huge \mapsto \: {5x}^{2} - 8x - 4 \\ \\ \bf \huge \mapsto {5x}^{2} - 10x + 2x - 4 \\ \\ \bf \huge \mapsto5x(x - 2) + 2( x- 2) \\ \\ \bf \huge \mapsto(5x + 2)(x - 2) \\ \\ \tt \therefore \: x = \frac{ - 2}{5} \: and \: \: x = 2 \\ \\ \sf{ \underline{ \underline{ \huge{ \blue {zeroes \: of \: the \: polynomial \: is \: \frac{ - 2}{5} \: and \: 2 \: }}}}}$

Answer 2

Step-by-step explanation:

$$\begin{lgathered}\tt \huge\underbrace {answer} \\ \\ \sf \: splitting \: the \: middle \: term \: \\ \\ \bf \huge \mapsto \: {5x}^{2} - 8x - 4 \\ \\ \bf \huge \mapsto {5x}^{2} - 10x + 2x - 4 \\ \\ \bf \huge \mapsto5x(x - 2) + 2( x- 2) \\ \\ \bf \huge \mapsto(5x + 2)(x - 2) \\ \\ \tt \therefore \: x = \frac{ - 2}{5} \: and \: \: x = 2 \\ \\ \sf{ \underline{ \underline{ \huge{ \blue {zeroes \: of \: the \: polynomial \: is \: \frac{ - 2}{5} \: and \: 2 \: }}}}}\end{lgathered}$$
