Answer:
(x - 3)² = -9
Solution:
Subtract seven from both sides. After you do that, simplify, then divide both sides by -4.
Also, quadractic bit of it is x = 3i + 3, x = -3i + 3.
x=3+3i, 3-3i
Explanation:
-4(x-3)²+7=43
(x-3)(x-3)= x²-6x+9
-4(x²-6x+9)+7=43
-4x²+24x-36+7=43
-4x²+24x-29=43
-4x²+24x-72=0
-x²+6x-18=0
Quadratic formula: -b+√(b²-4ac) / 2a
-(-6)+√((-6)²-4(1)(18)) / 2(1)
6+√(36-72) /2
6+√(-36) / 2
x=6+6i / 2
