Question

if a+1/a=4 so what will the answer for a²-4a+3​

Answer 1

Given:

• a=4 
• Equation a²+4a−3

To find:

• Value of the given equation  a²+4a−3

Solution:

$\sf{Putting \: values \: of  \: \bold{a=4}} \\ : \implies \sf{42+4×4−3} \\ : \implies \sf{16+16−3} \\ \sf : \implies \sf{32−3} \\ : \implies \underline{\boxed{ \frak{29}}} \pink\bigstar$

Then,

• Value of the given equation is 29

Thank you!

Answer 2

Answer:

$\frac{a + 1}{a} = 4$

$a + 1 = 4a$

$a = 4a - 1$

${a}^{2} - 4a + 3 = {(4a - 1)}^{2} - 4(4a - 1) + 3$

$= 16 {a}^{2} - 8a + 1 - 16a + 4 + 3$

$= 16 {a}^{2} - 24a + 8$
