Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. The quadratic formula is developed by applying factoring and the zero-product principle to the quadratic equation \(a x^{2}+b x+c=0\)
Determine whether statement "makes sense" or "does not make sense" and explain your reasoning. When solving \(f(x)>0,\) where \(f\) is a polynomial function, I only pay attention to the sign of \(f\) at each test value and not the actual function value.
$$\text { Solve: } x^{4}-8 x^{2}+15=0$$
$$\text { Solve for } y: \frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1$$
The longer leg of a right triangle exceeds the shorter leg by 1 inch, and the hypotenuse exceeds the longer leg by 7 inches. Find the lengths of the legs. Round to the nearest tenth of a inch.
