Step-by-step explanation:
let p of x=2x⁴-7x³-13x²+63x-45
prime factor of constant term 45=1*3*3*5
putting x=1
p(1)=2*1⁴-7*1³-13*1²+63*1-45
=2-7-13+63-45
=65-65
=0
since (x-1)is a factor of p(x)
x-1)2x⁴-7x³-13x²+63x-45(2x³-5x²-18x+45
+2x⁴-2x³
-5x³-13x²
-5x³+5x²
-18x²+63x
-18x²+18x
45x-45
45x-45
0
p(x)=(x-1)[2x³-5x²-18x+45]
=(x-1)x(2x²-5x-18+45)
=x(x-1)(2x²-5x+27)
HOPE THIS HELPS YOU
