Question

Worksheet 7
factoride the following expression.
1.x²+12x+27=​

Answer 1

Answer:

x² + 12x + 27 = 0

=> x² + ( 9 + 3 ) x + 27 = 0

=> x² + 9x + 3x + 27 = 0

=> x( x + 9 ) + 3( x + 9 ) = 0

=> ( x + 9 ) ( x + 3 ) = 0

x = -9 or -3

Answer 2

Answer:

x2 + 9x + 3x + 27 = 0

x(x + 9) + 3 (x + 9) = 0

( x + 9 ) ( x + 3 ) = 0

x = -9 or - 3
