Answer:
[tex]16x^2-9[/tex]
Step-by-step explanation:
[tex]\left(4x+3\right)\left(4x-3\right)[/tex]
We´ll Apply Difference Two Squares Formula:
- [tex]\left(a+b\right)\left(a-b\right)=a^2-b^2[/tex]
[tex]\longmapsto[/tex] [tex]\left(4x+3\right)\left(4x-3\right)[/tex]
[tex]\longmapsto[/tex] [tex]\left(4x\right)^2-3^2[/tex]
Apply exponent rule:
- [tex]\left(a\times \:b\right)^n=a^nb^n[/tex]
[tex]\longmapsto[/tex] [tex]4^2x^2-3^2[/tex]
[tex]\longmapsto[/tex] [tex]16x^2-9[/tex]

Answer:
16x^2 - 9
Step-by-step explanation:
(4x + 3)(4x - 3)
Using identity, (a + b) (a - b) = a^2 - b^2
here, a = 4x + 3 and b = 4x - 3,
therefore,
=> (4x) ^2 - (3)^2
=> 16x^2 - 9... ans
