-48 plugging in everything and using PEMDAS it should be -48
X²+3x-21=0
1) we solve this square equation:
x=[-3⁺₋√(9+84)] / 2=(-3⁺₋√93)/2
We have two solutions:
x₁=(-3-√93)/2
x₂=(-3+√93)/2
2) we compute the product of the 2 solutions found.
[(-3-√93)/2][(-3+√93)/2] =(-3-√93)(-3+√93) / 4=
=(9-93)/4=-84/4=-21
Answer: the product of the 2 solutions of this equation is -21
So, (6a - X)*5a = Y*(a^2) - 35a
<span>=> 6a*5a - X*5a = Y*(a^2) - 35a </span>
<span>=> 30(a^2) - X*5a = Y(a^2) - 35a
</span>30 = Y and
<span>X*5 = 35 or X = 7 </span>
Move all the x's to one side of the equation. This is a step necessary to solve this equation.
Subtract both sides by x.
Flip equation. We always want to have the variable written on the left side.
Subtract both sides by 26.
Divide both sides by 4 to finish this off.
That's your answer. Have an awesome day! :)
