Part One:
Solve the equation by completing the square.
x2 - 3x - 15 = -5
x2 - 17x = -10x - 6
Find the discriminant of each quadratic equation.
-10x2 - 6x + 5 = 0
2x2 + 6x + 1 = 0
Part Two:
Use the quadratic formula to solve each equation.
2x2 - 5x + 4 = 0
12x2 - 5x - 7 = 0
A.Solve the following algebraic expressions;
(i) y- 13 = 15- 2y
(ii) 12x -4 = 14 +10x
Solve the following Quadratic Equations by Factorization:
(iii) x2 + 5x รขยย 14 = 0
(iv) x2 +3x รขยย 4 = 0
Use the quadratic formula to solve for x"
2x^2 + 5x - 1 = 0
Please list the steps. Keep simple
