In a quadratic equation, the formula is: ax^2 + bx + c = 0
In the given formula 2x^2 + 4x -6 = 0:
a = 2, b = 4 and c = -6
Using the quadratic formula x1, x2 = -b+/-sqrt(b^2-4ac)/2a
Replace am b and c with their values and solve:
Now you have the 2 x values :
x1 = 1, x2 = -3
1^2 + -3^2 = 1 + 9 = 10
Answer: 10
Answer:
10
Step-by-step explanation:
→ Factorise equation
( 2x + 6 ) ( x - 1 )
→ Solve
x = -3 and 1
→ Find the value
