7 r^{2} - 14 r = - 7

r = 1

Solution steps

7 r^{2} - 14 r = - 7

Move

7

to the left side

7 r^{2} - 14 r + 7 = 0

Factor

7 r^{2} - 14 r + 7 : 7 (r - 1)^{2}

7 (r - 1)^{2} = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

r - 1 = 0

Solve

r - 1 = 0 : r = 1

The solution to the quadratic equation is:

r = 1

(2 x + 3) (x + 4) = 228

3 (4 x^{2} - 1) + 6 (- 2 x + 3) = - 7

5 x^{2} - 2 x - 35 = 0

4 n^{2} - 20 n + 16 = 0

220 - (16.5 - 2 x)^{2} = 99.9
