sqrt(25y^2-10y+1)=7

25 y^{2} - 10 y + 1 = 7

y = \frac{8}{5}, y = - \frac{6}{5}

Decimal Notation

y = 1.6, y = - 1.2

Solution steps

25 y^{2} - 10 y + 1 = 7

Square both sides:

25 y^{2} - 10 y + 1 = 49

25 y^{2} - 10 y + 1 = 49

Solve

25 y^{2} - 10 y + 1 = 49 : y = \frac{8}{5}, y = - \frac{6}{5}

y = \frac{8}{5}, y = - \frac{6}{5}

Verify Solutions:

y = \frac{8}{5}

True

, y = - \frac{6}{5}

True

The solutions are

y = \frac{8}{5}, y = - \frac{6}{5}
