5 d^{2} = 7 d

d = 0, d = \frac{7}{5}

Decimal Notation

d = 0, d = 1.4

Solution steps

5 d^{2} = 7 d

Move

7 d

to the left side

5 d^{2} - 7 d = 0

Factor

5 d^{2} - 7 d : d (5 d - 7)

d (5 d - 7) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

d = 0 or 5 d - 7 = 0

Solve

5 d - 7 = 0 : d = \frac{7}{5}

The solutions to the quadratic equation are:

d = 0, d = \frac{7}{5}

2 x^{2} + x + 1

15 x^{2} + 10 x = 0

1 5^{2} + b^{2} = 2 5^{2}

x^{2} - 8 = 56

y, - x^{2} + 6 x = y^{2} + 8 y
