Find the x-intercept(s) of y = 2x2 - 3x - 5.<br> A) -5 <br> B) 2 1/2, -1<br> C) 3, -5 <br> D) 5, -1

Answer:

$\large\boxed{B)\ 2\frac{1}{2},\ -1}$

Step-by-step explanation:

x-intercepts are for y = 0.

We have the equation:

$y=2x^2-3x-5$

Therefore

$2x^2-3x-5=0\\\\2x^2+2x-5x-5=0\\\\2x(x+1)-5(x+1)=0\\\\(x+1)(2x-5)+0\iff x+1=0\ \vee\ 2x-5=0\\\\x+1=0\qquad\text{subtract 1 from both sides}\\\boxed{x=-1}\\\\2x-5=0\qquad\text{add 5 to both sides}\\2x=5\qquad\text{divide both sides by 2}\\\boxed{x=2\frac{1}{2}}$

Answer:

Step-by-step explanation:

1) $5^{\frac{2}{3} }$ is in exponential form.

<u>Now, radical form is </u> $\sqrt[3]{5^{2} }$

2) $5^{\frac{1}{2} }$ is in exponential form.

<u>Radical form is </u> $\sqrt{5}$

3) $3^{\frac{2}{5} }$ is in exponential form.

<u> Radical form is </u> $\sqrt[5]{3^{2} }$

4) $3^{\frac{5}{2} }$ is in exponential form.

<u> Radical form is </u> $\sqrt{3^{5} }$
