Question

factorise x+16 from chapter polynomial​

Answer 1

Answer:

Step-by-step explanation:

x+16=0

x=-16

Answer 2

$(x + 4)^{2} = {x }^{2} + 2(x)(4) + {4}^{2}$

${x}^{2} + 8x + 16 = 0$

Now factorise it by taking the sum and product

Sum=8

Product=16

Factors=4,4

Therefore,

${x}^{2} + 4x + 4x + 16 = 0 \\ x(x + 4) + 4(x + 4) = 0 \\ = (x + 4)( x + 4) \\ = x = - 4$
