Answer: - 1.536 or - 8.464
Explanation:
Step 1: Rearrange the equation, by putting everything on the left hand side of the equation so that the quadratic formula can be applicable to the equation
x^2-10*x+25-(12)=0
Step 2: the quadratic formula
- B ± √ B2-4AC
x = ————————
2A
Where A= 1
B = 10
C = 13
B2 - 4AC = 100 - 52
= 48
10 ± √ 48
x = —————
2
- √ 48
x =(10-√48)/2=5-2√ 3 = - 1.536
x =(10+√48)/2=5+2√ 3 = - 8.464
Are the two solutions
