Question

If 2 and 1/2 are the zeroes of px^2 +5x+r then .​

Answer 1

$x = 2 \: in \: the \: equation \\ put \: the \: value \: of \: x = 2 \\ then \\ 4p + 5 \times 2 + r = 0 \\ = 4p + 10 + r = 0 \\ half \: byyourself$

Answer 2

Answer:

\begin{gathered}x = 2 \: in \: the \: equation \\ put \: the \: value \: of \: x = 2 \\ then \\ 4p + 5 \times 2 + r = 0 \\ = 4p + 10 + r = 0 \\ half \: byyourself \\ \end{gathered}

x=2intheequation

putthevalueofx=2

then

4p+5×2+r=0

=4p+10+r=0
