Step 1
Given: 6x45x221
To factor the given trinomial?
Using the fact that by letting x2=y (substitution method)
Step 2
6x45x221
Put x2=y6y25y21
=(3y-7)(2y+3)
=(3x27)(2x2+3) (by replacing y as x2)
Therefore, 6x45x221=(3x27)(2x2+3)
but still it is not factored interms of linear expressionie., the expression (2x2+3) can be factored into twopairs of complex number (x+i32)(xi32 which is absqrt in real number system here.
