Answer:
Y intersect and X intersect
Foils stands for first, outer, inner, last.
For example:
(3x + 5)(2x + 3)
Multiply the firsts together.
3x * 2x = 5x²
Now multiply the outer together.
3x * 3 = 9x
Now multiply the inners.
5 * 2x = 10x
Now multiply the lasts.
5 * 3 = 15
so the answer would be:
5x² + 9x + 10x + 15
5x² + 19x + 15
Hope this helps :)
Answer:
Once the rules of exponents are understood, you can begin solving more complicated expressions more easily. Recall that when you take a power to a power, you multiply the exponents, (xa)b= xa·b.
What happens when you raise an entire expression inside parentheses to a power? You can use the techniques you already know to simplify this expression.
(2a)4 = (2a)(2a)(2a)(2a) = (2 • 2 • 2 • 2)(a • a • a • a) = (24)(a4) = 16a4
Notice that the exponent is applied to each factor of 2a. So, we can eliminate the middle steps.
(2a)4 = (24)(a4), applying the 4 to each factor, 2 and a.
= 16a4
The product of two or more numbers raised to a power is equal to the product of each number raised to the same power.
(5, -2) because y=(x-5)^2-2 is really y=x^2-10x+23 after you foil then take the derivative which is y'=2x-10 solve for x and you get 5 then put 5 in the original equation and you get -2 so the answer is (5, -2)<span />
Answer:
Step-by-step explanation:
So first rewrite the inside of the parentheses as improper fractions:
÷ 
Now simplify the inside:
÷ 2
Which is:
