Answer» ( x - 3 ) ( x + 15 ) (- x - 5 ) ( x - 8 )( a + 11 ) ( a - 8 )( a + 3 ) ( a - 17 )( x + 9 ) ( x + 5 )Step-by-step explanation:1. x² + 12 x - 45 = x² + 15x - 3x - 45 = x (x+15) - 3 (x+15) = (x-3) (x+15)2. 40 + 3x - x² = - x² + 3x + 40 = - (x² – 3x – 40) = - ( x²– 8X + 5x – 40)= - [ x ( x - 8 ) + 5 ( x - 8 ) ]= - ( x + 5 ) ( x - 8 )= ( - x - 5 ) ( x - 8 )3. a^2 + 3a - 88Solving by SPLITTING Method:= a^2 + 3a - 88= a^2 + 11a - 8a - 88= a ( a + 11 ) - 8 ( a + 11 )= ( a + 11 ) ( a - 8 )4. a^2 - 14a - 51Solving by Splitting Method:a^2 - 14a - 51= a^2 - 17a + 3a - 51= a ( a - 17 ) + 3 ( a - 17 )= ( a + 3 ) ( a - 17 )5. x² + 14x + 45Solving by Splitting Method:= x² + 14x + 45= x² + 9x + 5x + 45= ( x² + 9x ) + ( 5x + 45)= x ( x + 9 ) + 5 ( x + 9 )= ( x + 9 ) ( x + 5 ) |
