Solve {l}{Delta=35^2-4*1}{a=7*{(-37)}}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { \Delta = 35 ^ {2} - 4 \cdot 1 }\\ { a = 7 \cdot {(-37)} }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Solve for Δ, a, b

$$b=-259$$

Solution Steps

Consider the first equation. Calculate 35 to the power of 2 and get 1225.

$$\Delta =1225-4\times 1$$

Multiply 4 and 1 to get 4.

$$\Delta =1225-4$$

Subtract 4 from 1225 to get 1221.

$$\Delta =1221$$

Consider the second equation. Multiply 7 and -37 to get -259.

$$a=-259$$

Consider the third equation. Insert the known values of variables into the equation.

$$b=-259$$

The system is now solved.

$$\Delta =1221 a=-259 b=-259$$
