5 b^{2} = 45 b

b = 0, b = 9

Solution steps

5 b^{2} = 45 b

Move

45 b

to the left side

5 b^{2} - 45 b = 0

Factor

5 b^{2} - 45 b : 5 b (b - 9)

5 b (b - 9) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

b = 0 or b - 9 = 0

Solve

b - 9 = 0 : b = 9

The solutions to the quadratic equation are:

b = 0, b = 9

4 (2 a + b)^{2} + 4 (2 a + b) - 24

2 (\frac{48}{3})^{\frac{1}{4}}

x^{2} - 27 x + 176 = 0

\frac{m ^{2} - 9}{m - 3}

3 x^{2} - 16 x + 5
