I am stuck on the formla for these

ANd the word question is confusing,

1.2z²-8=-4z

2.(t-3)²=-40

3.y²+1/3y=2/3

4.A right triangle has side lengths that areconsecutive even integers.Use the Pythagorean theorem to find the lengths of those sides. Remember:In a right triangle where a and b are the measures of the legs and c is the measure of the hypotenuse,

a²+b²=c²

Represent each side of the triangle in terms of the first side, setup an equation based on thepythagoreantheorem, solve the equation, and state the length of each side of the triangle
