Question

using identity (x+a) (x+b) = x squre +(a+b) x+ab to find (4x-5)(4x-1)​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

x=5/4 and x=1/4.

Step-by-step explanation:

(4x-5)(4x-1)=(4x^2)+4x(-5-1)+(-5×-1)Using above given identity

=16x^2-20x-4x+5

=16x^2-24x+5 this is quadratic equation by solving this we can get"x" values

16x^2-24x+5

16x^2-20x-4x+5

4x(4x-5)-1(4x-5)

(4x-5)(4x-1)

x=5/4 and x1/4

u can do directly without all this steps....
