I hope this helps you
1.k^2+5k-6=0
a=1
b=5
c= -6
disctirminant =b^2-4ac
disctirminant =5^2-4.1. (-6)
disctirminant =49
x1= -(5)+ square root of 49/2.1
x1=-5+7/2
x1=1
x2= -5- square root of 49/2.1
x2= -5-7/2
x2= -6

= π² = 9.8696</h3>
Explanation:
1.) Rewrite √24 =
Rewrite √54 =
Divide both terms by the denominator; √6 cancels. 2-3 = -1
2.) Rewrite as
×
The 3's cancel. 10/2 = 5√2 in the numerator.
√5 × √5 = 5 in the denominator. The 5's cancel.
That leaves √2 ≈1.4142
3.) Divide the terms in the numerator by the term in the denominator.
√2's cancel. 10π/2 = 5π 8π/2 = 4π
Subtract and we are left with π = 3.14159
4.)
The square roots are reciprocals. They multiply to 1
We are left with π × π = π² ≈ 9.8696
