Question

Use suitable identites to find the following products: (¡) (x+4)(x+10)​

Answer 1

Answer:

x= -4 or -10

Step-by-step explanation:

by properties of production,

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

x² + 10x + 4x + 40

x² + 14x + 40 ( by middle term splitting)

x² + 4x + 10x + 40

X ( x+ 4) + 10 ( X + 4) ( on taking common)

(x+4) (x+10)=0

X = -4 or -10

Answer 2

(x+4)(x+10)

= (x)² + (4+10)x + (4)(10)

= x² + 14x + 40
