Question

1) Solve ( 5x - 3)( 5x - 2) using a suitable Identity​

Answer 1

Step-by-step explanation:

by identity

a^2 -b^2 =(a+b)(a-b)a

2

−b

2

=(a+b)(a−b)

_____________________________

(5x-3)(5x+3)

(5x)^2 -3^2(5x)

2

−3

2

25x^2 - 9

Answer 2

Answer:

25x²-30x+9

Step-by-step explanation:

(5x-3)(5x-3)

we use indenty (a-b)²= a²-2ab+b²

(5x-3)

5x²-2(5x)(3)+3²

25x²-30x+9
