Question

sove this (6x+5)(6x+6)=

Answer 1

Heya!

Here is yr answer.....


=>(6x+5) (6x+6)

[ (x+a)(x+b) = x²+(a+b)x+ab ]

x = 6x , a = 5 , b = 6


=> (6x)² + (5+6)6x +(5)(6)

=> 36x² + (11)6x + 30

=> 36x² + 66x + 30


Hope it helpz.....

Answer 2

let's take y=(6x+5) .then (6x+5)(6x+6) =y(y+1) =
${y}^{2} + y$
=>
${(6 x + 5)}^{2} + (6x + 5)$
use this formula to find square of a polynomial
${(x + y)}^{2} = {x }^{2} + {y}^{2} + 2xy.$
=> thus
${(6x)}^{2} + {5}^{2} + 2(6x)(5) + 6x + 5$
=>
$36 {x}^{2} + 25 + 60x + 6x + 5$
=>
$36 {x}^{2} + 66x + 30$
is the answer .Hope it helps you fair47...
