Question

Use suitable identitie
v (x+4) (x + 10)​

Answer 1

Answer:

(i) Using identity,

[(x + a) (x +

b) = x² + (a + b) x +

ab]

In (x + 4) (x + 10),

a = 4 &

b = 10

Now,

(x + 4) (x + 10)

= x² + (4 + 10)x + (4 × 10)

= x² + 14x+

40

Answer 2

Answer:

Step-by-step explanation:

(x+4)(x+10)

(x*x + x*10 + 4*x + 4*10)

$x^{2}$ + 10x + 4x + 40

$x^{2}$ + 14x + 40.

Distributive property.
