Question

( 3 - 2x ) ( 3 + 2x ) ​

Answer 1

Answer:

a^2-2ab+b^2

3^2-2(3)(2x) +2x^2

6^2-12x+4x^2

Answer 2

$(a - b)(a + b) \\ = (a )^{2} - ( b)^{2} \\ = {a}^{2} - {b}^{2}$

So, we will expand (3 - 2x)(3 + 2x) in the same way.

so,

$(3 - 2x)(3 + 2x) \\ = ({3})^{2} - ({2x})^{2} \\ = 9 - (2 \times 2 \times x \times x) \\ = 9 - 4 {x}^{2}$

so, the Answer is 9 - 4x²

Hope this helps you.
