Answer:The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.

Step-by-step explanation: 6x² + 11x - 35 = 0.

2x² - 4x - 2 = 0.

-4x² - 7x +12 = 0.

20x² -15x - 10 = 0.

x² -x - 3 = 0.

5x² - 2x - 9 = 0.

3x² + 4x + 2 = 0.

-x² +6x + 18 = 0.

How can systems of linear equations with two variables be solved using algebraic methods?
erik [133]

Answer: The systems are solved by solving for one variable in one of the equations, then substituting that equation into the second equation. Solve for a in the second equation, then substitute the second equation into the first. The Elimination Method: Both equations are in standard form:            Ax + By = C.
