Question

Factorise: x^2+1/4x^2+1-7x-7/2x
7​

Answer 1

Step-by-step explanation:

${x}^{2} + \frac{1}{4} {x}^{2} + 1 - 7x - \frac{7}{2} x7 \\ \frac{1}{4} {x}^{4} + \frac{7}{2} 6 {x}^{2} 7 \\ \frac{15}{4} 6 {x}^{6} 7 \\ \frac{15}{4} \times 7 \times 6 {x}^{6} \\ \frac{15}{4} \times \frac{168}{4} \times {x}^{6} \\ 2520 {x}^{6}$
