Solve the equation 0= x^2 + 4x– 12 by graphing.

DiKsa [7]

Answer:

The answer is -6 or 2

Step-by-step explanation:

${x}^{2} + 4x - 12 = 0 \\ 4 \div 2 = 2 \\ x1 = - 2 - u \\ x2 = - 2 + u \\ x1x2 = ( - 2 - u)( - 2 + u) = - 12 \\ 4 - {u}^{2} = - 12 \\ 4 + 12 = {u}^{2} \\ 16 = {u}^{2} \\ \sqrt{16} = + \: or - \sqrt{ {u}^{2} } \\ u = + or - 4 \\$

$x1 = - 2 - 4 = - 6 \\ x2 = - 2 + 4 = 2$

2 + 2 + 9 x 19 = FMOTT

tatuchka [14]

Answer:

175

Step-by-step explanation:

I would assume you are asking what 2 + 2 + 9 * 19, and that the image is merely advertisement and irrelevant info for the question.

Anyway, we are solving 2 + 2 + 9 * 19.

PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction:

That is the order of operations. We can apply that in your equation.

Since multiplication comes before addition/subtraction, we are solving 9 * 19 first. That gives 171.

Now for addition:

2 + 2 + 171 = 4 + 171.

4 + 171 = 175.

Thus, our final answer is 175.
