Question

If p of x = 2 x square - 4 x + 3 will it be of 2 - 3 into bracket - 1 + 1 upon 2

Answer 1

p×x=2x²-4x+3×2-3(-1+1/2)

px=2x²-4x+6-3(-1+1/2)

px=2x²-4x+3(-2+1/2)

px=2x²-4x+3(-1/2)

x=2x²-4x-3/2

x+4x=2x²-3/2

5x=2x²-3/2

5x=(4x²-3/2)

5x2=4x²-3

10x=4x²-3

x-4x²= -3×10

x-4x²=-30

x-4x=√-30

3x= √30

3x=5.47

x=(5.47)÷3

x=1.82
