1.	Find the value of the expression 2x2 – 4x + 5 when x = 1
Answer» Given expression is 2x² – 4x + 5 When x = 1, then = 2(1)² – 4(1) + 5 = 2 × 1 – 4 + 5 = 2 – 4 + 5 = 3 When x = 1, then 2x² – 4x + 5 = 3

Answer»

Given expression is 2x² – 4x + 5

When x = 1, then

= 2(1)² – 4(1) + 5

= 2 × 1 – 4 + 5

= 2 – 4 + 5 = 3

When x = 1, then 2x² – 4x + 5 = 3
