Question

find the value of A and B if 2 x square - 5 x + 3 is the factor of x power 4 + 2 X power 3 + 5 X power 2minus 5 b

Answer 1

solution

x³+5²-10x+30

(x-3)√x∧4+2x³+5x²-5b

x∧4-3x³

5x³+5x²-5b

-5x³-15x²

-10x²-5b

-10x-30x

30x-5b

-30x-90

90-5b

⇒ the value of A and B are require as

A=90 b=-5
