Answer:
x=−1/2+1/2√10 or -1/2+-1/2√10
Step-by-step explanation:
4x2+4x−2=7
Step 1: Subtract 7 from both sides.
4x2+4x−2−7=7−7
4x2+4x−9=0
For this equation: a=4, b=4, c=-9
4x2+4x+−9=0
Step 2: Use quadratic formula with a=4, b=4, c=-9.
x=
−b±√b2−4ac
2a
x=
−(4)±√(4)2−4(4)(−9)
2(4)
x=
−4±√160
8
x=
−1/2
+
