Question

Q.)Find the value of x⁴–3x²+2x–1 when x = 2​

Answer 1

Step-by-step explanation:

${x}^{4} - 3 {x}^{2} + 2x - 1 \\ \\ x = 2 \\ \\ \\ \\ {2}^{4} - 3 \times {2}^{2} + 2 \times 2 - 1 \\ 16 - 3 \times 4 + 4 - 1 \\ 16 - 12 + 3 \\ 16 + 3 - 12 \\ 7$

Answer 2

Answer:

if x = 2 ,

==> (2)⁴ - 3(2)² +2 ×2 - 1 .

==> 16 - 12 + 4 -1

==> 7 ans .
