[tex]\huge \fbox \pink {A}\huge \fbox \green {n}\huge \fbox \blue {s}\huge \fbox \red {w}\huge \fbox \purple {e}\huge \fbox \orange {r}[/tex]

[tex]x = 3[/tex]

[tex] {2x}^{3} + {x}^{2} - x \\ = 2(3) {}^{3} + (3) {}^{2} - 3 \\ = 2 \times {3}^{3} + {3}^{2} - 3 \\ = 2 \times 27 + 9 - 3 \\ = 54 + 9 - 3\\ = 63 - 3 \\ = 60 [/tex]

ʰᵒᵖᵉ ⁱᵗ ʰᵉˡᵖˢ

[tex] \huge\blue{ \mid{ \underline{ \overline{ \tt ꧁❣ ʀᴀɪɴʙᴏᴡˢᵃˡᵗ2²2² ࿐ }} \mid}}[/tex]

2x3 + x2 , x = 3
= 2*3*3 + 3*2
= 18 + 6
= 24
Hence 24 is the answer
