(4x + 3)(4x - 3)<br> Help pls
tekilochka [14]

Answer:

16x^2-9

Step-by-step explanation:

\left(4x+3\right)\left(4x-3\right)

We´ll <u>Apply Difference Two Squares Formula:</u>

  • \left(a+b\right)\left(a-b\right)=a^2-b^2

\longmapsto \left(4x+3\right)\left(4x-3\right)

\longmapsto \left(4x\right)^2-3^2

<u>Apply exponent rule</u>:

  • \left(a\times \:b\right)^n=a^nb^n

\longmapsto 4^2x^2-3^2

\longmapsto 16x^2-9
