Question

Find the value of a and b when x=10

Answer 1

Step-by-step explanation:

a=5*100/2=500/2

a=250

b=2*100(10-5)/10*10

=200*5/100

=1000/100

b=10

Answer 2

Answer:

Required value of a is 250 and value of b is 10

Step-by-step explanation:

Given,

$a = \frac{5 {x}^{2} }{2} \\ b = \frac{2 {x}^{2}(x - 5) }{10x}$

We want to find value of a and b when x = 10.

We are putting x = 10 in a and b.

So,

$a = \frac{5 \times {10}^{2} }{2} \\ a = \frac{5 \times 100}{2} \\ a = 5 \times 50 \\ a = 250$

and

$b = \frac{2 \times {10}^{2}(10 - 5) }{10 \times 10} \\ b = \frac{2 \times 100 \times 5}{100} \\ b = 2 \times 5 \\ b = 10$

This is a problem of value putting part of Algebra.

Some important Algebra formulas:

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
