Step-by-step explanation:
We'll use Quadratic formula to solve this equation:
______________________
→ Add 10 from both sides:
→ Subtract -10 from -10= 0
→ Subtract -10 from -13:
Now, Equation is in standard from ax^2+bx+c=0, we'll solve it using Quadratic formula:
Square -7, you'll get 49, multiply -4 * 2= 8, and than -8 * -3= 24
→ Add 49 + 24= 73
→ Multiply 2 * 2= 4
