2(χ+4)(2x+5)=0

Solution

2 (χ + 4) (2 x + 5) = 0

Solution

χ = - 4, x = - \frac{5}{2}

+1

Decimal Notation

χ = - 4, x = - 2.5

Solution steps

2 (χ + 4) (2 x + 5) = 0

Using the Zero Factor Principle:

If

ab = 0

then

a = 0

or

b = 0

χ + 4 = 0 or 2 x + 5 = 0

Solve

χ + 4 = 0 : χ = - 4

Solve

2 x + 5 = 0 : x = - \frac{5}{2}

The solutions are

χ = - 4, x = - \frac{5}{2}
