Question

Use the identity (a + b)(a − b) = a² − b² to find the products:
(i) (x + 6)(x − 6);
(ii) (3x + 5)(3x − 5);
(iii) (2a + 4b)(2a − 4b);
(iv) $(\frac{2x}{y} +1) (\frac{2x}{3} -1)$

Here is your answer⤵⤵⤵⤵⤵

✔
${x}^{2} - 36$
✔
$9 {x}^{2} - 25$
✔
$4 {a -}^{2} - 16 {b}^{2}$

✔4x^2/y^2-1

Answer 2

Answer:

Step-by-step explanation:

i (x+6)(x-6)=xXx-6X6

=x square-36

(3x+5)(3x-5)

Now,

a=3x

b=5

(3x+5)(3x-5)=3xX3x-5X5

=9x square-25

(2a+4b)(2a-4b)=2aX2a-4bX4b

=4a square-16b square

I hope u got the ans!

All the best
