Question

simplify (5x-2)
(5x+6) by using suitable identity

​

Answer 1

Answer:

Step-by-step explanation:

(x + a)(x + b) = x^2 + ab + x(a + b)

(5x-2) (5x+6) = (5x^2) + (-2*6) + 5x(6-2)

                    = 25x^2 -12 + 20x

Answer 2

Answer:

(in the attachment )

Step-by-step explanation:

1. Firstly we have found the nearest identity of the given question.
2. Accordingly we found that it is (x+a)(x+b) identity where {x = 5 x} {a = -2} and {b =6 .}
3. Following the expansion as (x² + (a+b)x + ab) and substituting the values in their correct places ; we have simplified by using simple mathematical operations like Multiplication , addition and understanding of signs .
4. In this way we got our final answer as :

25x² + 20x - 12
