Question

me ajudem novamente, Coloque na forma ax² bx+ c=0

A) 5x+3x²=4x-7
B) x(2x-3)=4x-1
C) 4x(x+3)+3=0

Answer 1

Forma: ax² + bx + c = 0

a)

5x + 3x² = 4x - 7

3x² + 5x - 4x + 7 = 0

3x² + x + 7 = 0

b)

x.(2x - 3) = 4x - 1

2x² - 3x - 4x + 1 = 0

2x² - 7x + 1 = 0

c)

4x.(x + 3) + 3 = 0

4x² + 12x + 3 = 0

Answer 2

A)3x²+x+7=0
B)2x²-7+1=0
C)4x²+12x+3=0
