Question

7. Factorize the following algebraic expressions by splitting the (i) x² 21x+1o8   ​

Rose · Answer

Step-by-step explanation:     {x}^{2}  - 21x + 108       {x}^{2}  - 12x - 9x + 108 = 0    x(x-12)-9(x-12)=0   (x - 12)(x - 9) = 0   x=12 or 9

Sarah · Answer

x^2+21x+108    x2+12x+9x+108  x(x+12)+9(x+12)  =(x+12)(x+9)
