Find the value of x for the triangle

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

Solve each quadratic equation by factoring and using the zero product property. 14x - 49 = x^2

Solve for x where 0 equation: cot^2x+2cotx+1=0
