write each quadratic equation in standard form.

1) (2x+7)(x-1)=0
2) (x-4)²+8=0
3) (x=2)²=3(x+12)
4) (2x-1)²=(x+1)²
5) 2x(x+4)=(x-3)(x-3)

We just transfer all to one side and multiply.

1) 2x²+5x-7=0

2) x²-8x+16+8=0
x²-8x+24=0

3) x²+2x+4=3x+36
x²-x-32=0

4) 4x²-4x+1 = x²+2x+1
3x²-6x=0
x²-2x=0

5) 2x²+8x=x²-6x+9
x²+14x-9=0
