How do you solve 4b^2+8b+7=4 using the quadratic formula

lina2011 [118]

$
4b^2+8b+7=4\\
4b^2+8b+3=0\\\\
x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\
x=\dfrac{-8\pm\sqrt{8^2-4\cdot4\cdot3}}{2\cdot4}\\
x=\dfrac{-8\pm\sqrt{64-48}}{8}\\
x=\dfrac{-8\pm\sqrt{16}}{8}\\
x=\dfrac{-8\pm4}{8}\\
x=\dfrac{-2\pm1}{2}\\
x=\dfrac{-1}{2 }\vee x=\dfrac{-3}{2}\\
x=-\dfrac{1}{2 }\vee x=-\dfrac{3}{2}$

What is the difference? 4y+6/y-5 - 2y+1/y-5

nalin [4]

Answer:

$\frac{2y+5}{y-5}$

Step-by-step explanation:

Since both fractions have a common denominator then subtract the numerators leaving the denominator, that is

$\frac{4y+6-(2y+1)}{y-5}$

= $\frac{4y+6-2y-1}{y-5}$

= $\frac{2y+5}{y-5}$
