Question

it x=2 the value of x^2+2x+1 is... option ----(a) 6 (b) 8 (c) 9​

Answer 1

Given:

• x²+2x+1
• x = 2

To finD:

• value of expression on the given value of x

Solution:

We are given expression is x²+2x+1 and the value of x is 2. To find value of expression on the given value of x, we need to put the value of x on the place of x in expression.

Putting value of x :

$\large{\sf{\:\:\:x²+2x+1}}$

$\large{\implies{\sf{2²+(2×2) +1}}}$

$\large{\implies{\sf{(2×2)+4+1}}}$

$\large{\implies{\sf{4+4+1}}}$

$\large{\implies{\sf{9}}}$

Therefore,

$\large{\boxed{\mathfrak{\blue{Value\:of\: expression\:on\:the\:given\: value\:of\:x\:is\:\sf{9}}}}}$
