Answer: -15

The question asks you to find the "product," which means the result of multiplying. Both the word "product" and the parentheses indicate that you have to multiply.

Since it's a negative (-) multiplied by a positive (+), your product will be negative (-).

So, -3(5) = -15.

What is 2x2+11x-15=0

Elanso [62]

$2x^{2} + 11x - 15 = 0$

Use the quadratic equation:
$x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}$
$= \frac{-11 \pm \sqrt{121 - 4(2)(-15)}}{4}$
$= \frac{-11 \pm \sqrt{121 + 120}}{4}$
$= \frac{-11 \pm \sqrt{241}}{4}$

$\therefore x = \frac{-11 + \sqrt{241}}{4}$
or $x = \frac{-11 - \sqrt{241}}{4}$

There are two trees in a garden (A and B) and on both trees are some birds.

olga55 [171]

"If one of you comes to our tree, then our population will be double that of yours."

So $A+1 =2\times (B-1)

A+1 = 2B - 2$

"If one of you comes here, then our population will be equal to that of yours."

$A-1 = B+1$

Rearranging these to make A the subject gives:

$A = 2B-3$
$A = B +2$

Then solve for B:

$2B - 3 = B + 2
B = 5$

Substitute B back in to an equation:

$A = B + 2
A = 5 + 2
A = 7$

So there are seven birds in A, and 5 birds in B
