Question

Find the value of y^2+y-5 at y=2​

Answer 1

Given

• Equation → y² + y - 5
• Value of y is 2.

⠀

To find

• Value of the Equation.

⠀

Solution

• Here the value of y is 2, that is given in the question. We will put the value of y in the equation and find the whole value.

⠀

$\large{\tt{\longmapsto{y^2 + y - 5}}}$

⠀

$\large{\tt{\longmapsto{(2)^2 + 2 - 5}}}$

⠀

$\large{\tt{\longmapsto{4 + 2 - 5}}}$

⠀

• According to Bodmas, we will add first, then subtract.

⠀

$\large{\tt{\longmapsto{6 - 5}}}$

⠀

$\implies{\boxed{\bf{\orange{Value = 1}}}}$

⠀

Hence,

• The total value is 1.

Answer 2

Question:-

Find the value of y²+y-5 at y=2

Answer:-

• The value of Given algebraic expression is 1.

To find :-

• value of algebraic expression

Solution:-

• y = 2

According to question,

$\large { \tt : \implies \: \: \: \: \: \: \: {y}^{2} + y - 5}$

$\large { \tt : \implies \: \: \: \: \: \: \: {2}^{2} + 2 - 5}$

$\large { \tt : \implies \: \: \: \: \: \: \: 4 + 2 - 5}$

$\large { \tt : \implies \: \: \: \: \: \: \: 6 - 5}$

$\large { \tt : \implies \: \: \: \: \: \: \: 1}$

Hence,

• The value of Given algebraic expression is 1.
