Question

factorise : × square root 2 - 7×+10​

Answer 1

Answer:

x=5 & x=2

Step-by-step explanation:

$x {}^{2} - 7x + 10 = 0 \\ x {}^{2} - 5x - 2x + 10 = 0 \\ (x {}^{2} - 5x) - (2x - 10) = 0 \\ x(x - 5) - 2(x - 5) = 0 \\ (x - 5)( x - 2) = 0 \\ either \\ x - 5 = 0 \\ x = 5 \\ or \\ x - 2 = 0 \\ x = 2$
