Question

factorise please!!!​

Answer 1

9(x^2+x)(7x ^2+7x+2)

= 63x^4 + 126x^3 + 81x^2 + 18x

Answer 2

Solution:-

=> 1 - 9( x² + x ) ( 7x² + 7x + 2)

= 1 - ((9•(( x² )+x))•(( 7x²+7x)+2 ))

= 1 - (9x • (x + 1) • (7x² + 7x + 2))

= 1 - 9x • (x + 1) • (7x² + 7x + 2)

= -63x^4 - 126x^3 - 81x^2 - 18x + 1

= -1*(63x^4 + 126x^3 + 81x^2 + 18x - 1)

i hope it helps you....
