Question

2 b ² + 12 b +35
Factorise the following expression

Answer 1

Answer:

The expression is not factorable with rational numbers.

${2b}^{2} + 12b + 35$

Answer 2

Let, compare given expression with

{ a^2 + 2ab + b^2 = (a + b)^2 }

So, (1.45b)^2 + 2 (1.45b) ( 5.95 ) + ( 5.95)^2

= (1.45b + 5.95)^2 approx
