Nellie is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect?

5 0

For the answer to the question above, I think i've seen this question before.
If we substitute 13 to f(x) and get a value for x, then the two equations will intersect. So,
f(x) = x^2 + 6x +10
13 = x^2 + 6x+ 10
x^2 + 6x - 3 = 0

Solving the quadratic equations:
The roots of the equation is
x = 0.4641 and
x = -6.4541

Therefore, the line will intersect with the quadratic function.

Which expressions are differences of squares?

Lina20 [59]

Difference of 2 perfec squares is
(a^2)-(b^2)

if the exponents are both even and the coeficient (the number in front) are perfect squares, then it is difference t 2 perfect squares

first one
8 is not perfect square

2nd one
(4e^4)^2-(9g^2)^2

third
25 is odd, so it cannot be split up into 2 nice numbers

4th
(11m^9)^2-(3n^5)^2

Step 1. Factor out common terms in the first two terms, then in the last two terms.

2x^2(x - 5) -5(x - 5)

Step 2. Factor out the common term x - 5

(x - 5)(2x^2 - 5)
