Step-by-step explanation:
x-y^x-y
2-(-2)^2-(-2)
2-(-2)^2+2
2-(-2)^4
2-(16)
=-14
A. 2x^2 - 3x + 10 = 2x + 21
2x^2 - 3x - 2x + 10 - 21 = 0
2x^2 - 5x - 11 = 0 (quadratic equation)
2x^2 - 6x - 7 = 2x^2
2x^2 - 2x^2 - 6x - 7 = 0
-6x - 7 = 0 (not a quadratic equation)
5x^2 + 2x - 4 = 2x^2
5x^2 - 2x^2 + 2x - 4 = 0
3x^2 + 2x - 4 (quadratic equation)
5x^3 - 3x + 10 = 2x^2
5x^3 - 2x^2 - 3x + 10 = 0 (not a quadratic equation)
Therefore, options a and c can be solved using the quadratic formula.
Answer:
y= -1 or y equals negative 1
Step-by-step explanation:
-4(y) (-4)(-2) = 12
-4y + 8 = 12
-4y = 4
divide 4 by both sides
-y = 1
y= -1
