Question

Find the product.
(i) (5 - 2x) (3 + x)
(iii) (a + b)(a + b)​

Answer 1

Answer:

(i) 15 - x - 2x^2

(ii) a^2 + 2ab + b^2

Step-by-step explanation:

(i) (5-2x)(3+x)

5(3+x) - 2x(3+x)

15 + 5x - 6x - 2x^2

15 - x - 2x^2

(ii) (a+b)(a+b)

(a+b)^2

a^2 + 2ab + b^2

Answer 2

Answer:

(a) -2x²-x+15

(b) a²+b²+2ab

Step-by-step explanation:

(a)

   (5 - 2x)(3 + x)

   5(3+x)-2x(3+x)

   15+5x-6x-2x²

   -2x²-x+15

(b)

   (a+b)(a+b)

   a(a+b)+b(a+b)

   a²+ab+ba+b²

   a²+b²+2ab
