What is the product?(-2d^2+s)(5d^2-6s)
zimovet [89]
(-2d² + s)(5d² - 6s)

Simplify.

(-2d² × 5d²) + (-2d² × 6s) + (s × 5d²) + (s × -6s)

Simplify.

-10d² + (-12d²s) + (5d²s) + (-6s²)

Take out the parenthesis.

-10d² - 12d²s + 5d²s - 6s²

Combine like terms.

-10d² + (-12d²s + 5d²s) - 6s²

Simplify.

-10d² - 7d²s - 6s²

the sum of two numbers is zero. when 15 times the smaller numbers is added to 10 times the larger, the result is 1. find the two
EleoNora [17]

We have two numbers say a, b. And a system of equations.

a+b=0\wedge\dfrac{a+b}{15}+10(a+b)=1

It looks a bit intimidating but it's actually very easy.

Instead of term a + b in the second equation we can say it's zero because the first equation describes a + b as being equal to 0.

So,

\dfrac{0}{15}+10\cdot0=1\Longrightarrow 0+0=1

The above equation is not true therefore numbers a and b do not exists in the real number domain.

a,b\notin\mathbb{R}

No solution.

Hope this helps.
