5x2 + 12x + 7 = 0

This equation can be factored : (5x + 7) (x + 1) = 0

The equation equals zero when either 5x + 7 = 0 or x + 1 = 0

When 5x + 7 = 0 then 5x = -7 : x = -7/5 or -1.4

When x + 1 = 0 then x = -1

The solutions or roots of this equation are x = -7/5 and x = -1

Q: How do I work out 5xsquared plus 12x plus 7 equals 0?

The question cannot be answered because the ratio of the polynomials cannot simplify to "3x-12x plus 1" since that is not a simplified form: it simplifies to -9x + 1.

12x + 31 = 2x + 1710x = -14x = - 1.4

It is an equation.

30+12x = 6(5+2x)

12x = x + 3 11x = 3 x = 3/11

It is an equation.

30+12x = 6(5+2x)

12x = x + 3 11x = 3 x = 3/11

x=5

6x + 12x + 2x = 80 20x = 80 x = 4

9x + 2 = 12x + 14 -3x = 12 x = -4

12x - 8 = 10x + 42x = 12x = 6
