Solve for A
A=\left(1-5x\right)\left(2x+7\right)
Solve for x (complex solution)
x=\frac{\sqrt{1369-40A}-33}{20}
x=\frac{-\sqrt{1369-40A}-33}{20}
Solve for x
x=\frac{\sqrt{1369-40A}-33}{20}
x=\frac{-\sqrt{1369-40A}-33}{20}\text{, }A\leq \frac{1369}{40}

A=\left(5x-1\right)\left(-2x-3-4\right)
Combine x and -3x to get -2x.
A=\left(5x-1\right)\left(-2x-7\right)
Subtract 4 from -3 to get -7.
A=-10x^{2}-33x+7
Use the distributive property to multiply 5x-1 by -2x-7 and combine like terms.
