Question

14. Simplify the expression and evaluate: x (x - 3) + 2 for x = 1.​

Answer 1

Answer:

x(x-3)+2

2x-3x+2

-1x+2

-1x=-2

x= 2/1

so

x=1

Answer 2

Answer:

x ( x - 3 ) + 2 = x × x - x × 3 + 2

= ( x - 3 ) + 2

$x^{2}$ - 3x + 2

for x = 1

putting x = 1 in expression

$x^{2}$ - 3x + 2 = $1^{2}$ - 3 × 1 + 2

= 1 - 3 + 2

= ( 1 + 2 )  - 3

= 3 - 3

= 0
