Question

If p= 9 , find the value of : p^2 - 4 p^2 + p

Answer 1

p^2 - 4p^2 + p

= -3p^2 + p

= -3(9)^2 + 9

= -3(81) + 9

= -243 + 9

= (-234)

Answer 2

Answer is - 234

Given equation =

${p}^{2} - 4 {p}^{2} + p \\ \\ = - 3 {p}^{2} + p$

Putting P = 9 on given equation:-

$- 3( {9)}^{2} + 9 \\ \\ = - 3(81) + 9 \\ \\ = - 243 + 9 \\ \\ = - 234$
