PILNE!

1. Wyznacz a i b tak, aby wielomiany w i a były równe.

w(x) = 3x³ - 4x² + 5x + 6

a(x) = 3x³ + 2ax² + 5x - 3b

2. Wyznacz a i b tak, aby wielomiany w i g były równe.

w(x) = x³ + 5x² + 3x - 7

g(x) = x³ - 2ax² + bx - 7

berta92

1.w(x)=a(x)

3x³-4x²+5x +6=3x³ +2ax² + 5x -3b

-4x²=2ax² / ÷x²

-4=2a / ÷2

a = -2

6= -3b/ ÷(-3)

b = -2

2. w(x)=g(x)

x³ +5x² +3x-7

x³- 2ax² +bx - 7

5x²= -2ax² / ÷x²

5= -2a /÷(-2)

a=2,5

3x=bx

b=3
