(1/2a - 2/3b) ( 3/5a + 2/3b) multiply the following

11111nata11111 [884]

Answer:

Step-by-step explanation:

$(\dfrac{1}{2}a-\dfrac{2}{3}b)(\dfrac{3}{5}a+\dfrac{2}{3}b)=\dfrac{1}{2}a*(\dfrac{3}{5}a+\dfrac{2}{3}b) - \dfrac{2}{3}b*(\dfrac{3}{5}a+\dfrac{2}{3}b) \\\\\\= \dfrac{1}{2}a*\dfrac{3}{5}a + (\dfrac{1}{2}a*\dfrac{2}{3}b) - \dfrac{2}{3}b*\dfrac{3}{5}a- \dfrac{2}{3}b*\dfrac{2}{3}b\\\\\\=\dfrac{3}{10}a^{2} + \dfrac{1}{3}ab - \dfrac{2}{5}ab -\dfrac{4}{9}b^{2}\\\\=\dfrac{3}{10}a^{2} +\dfrac{1*5}{3*5}ab-\dfrac{2*3}{5*3}-\dfrac{4}{9}b^{2}\\\\\\$

$=\dfrac{3}{10}a^{2}+\dfrac{5}{15}ab-\dfrac{6}{15}ab -\dfrac{4}{9}b^{2}\\\\=\dfrac{3}{10}a^{2}-\dfrac{1}{15}-\dfrac{4}{9}b^{2}$

If rhe discriminant of a quadratic equation is equal to -8 which statement describes the roots

Nastasia [14]

Answer:

Step-by-step explanation:

Given

$Discriminant = -8$

Required

Determine the type of roots

Represent Discriminant with D; such that

$D = -8$

D is calculated as thus

$D = b^2 - 4ac$

And it has the following sequence of results

When $D > 0;$ then the roots of the quadratic equation are real but not equal

When $D = 0;$ then the roots of the quadratic equation are real and equal

When $D < 0;$ then the roots of the quadratic equation are complex or imaginary

Given that $D = -8$ ; This means that $D < 0;$ and base on the above analysis, we can conclude that the roots of the quadratic equation are complex or imaginary
