Question

Match the following:
(i) a0. (a) a² – 6²
(ii) (a + b)2 (b) x2 + (a + b)x + ab
(iii) (a - b)2 (c) a² + 2ab + b2
(iv) (a - b)(a + b)
(d) a? – 2ab + b2
(v) (x + a)(x + b)
(e) 1​

Answer 1

Answer:

(i) - (e)

(ii) - (c)

(iii) - (d)

(iv) - (a)

(v) - (b)

Step-by-step explanation:

(i) a⁰ = 1, a ≠ ±1,0

Hence (e)

(ii) (a + b)² = a² + 2ab + b²

Hence (c)

(iii) (a - b)² = a² - 2ab + b²

Hence (d)

(iv) (a - b)(a + b) = a² - ab + ab - b²

=> (a - b)(a + b) = a² - b²

Hence (a)

(v) (x + a)(x + b)

=> x² + ax + bx + ab

=> x² + x(a + b) + ab

Hence (b)

Hence the correct answer is :

(i) - (e)

(ii) - (c)

(iii) - (d)

(iv) - (a)

(v) - (b)
