Question

use suitable identity solve this (a+2) (a+3)​

Answer 1

Answer:

4(a+5/2)² - 1

Step-by-step explanation:

(a+2)(a+3) = a² + 5a + 6 .         [multiplying both]

Using Completing square method

a² + 5a + (5/2)² - (5/2)² + 6        [adding and multiplying the square of 5/2]

[a+5/2]² - (25 + 24)/4 .               [identity: (a+b)² = a² + 2ab + b²]

[a+5/2]² - 1/4

= 4[a+5/2]² - 1 .                          [multiplying the whole by 4]

∴ (a+2)(a+3) = 4(a+5/2)² - 1
