Question

ब्रैकेट 4एक्स - 5 ब्रैकेट ब्रैकेट 4 एक्स प्लस 5 बाय ब्रैकेट​

Answer 1

Answer:

You mean to say,

P(x) = [ 4x - 5 ] [ 4x + 5 ]

Now expanding it ,

= 4x ( 4x - 5 ) + 5(4x+5)

= 16x² - 20x + 20x + 25

= 16x² + 25

This the simplified form.

16x² + 25 = [4x +- 5]²

I HOPE ITS HELPFUL TO YOU.
