You just have to plug in -4 into
f(x) = 2 - 3x
This implies that,
f( - 4) = 2 - 3( - 4)


f( - 4) = 2  + 3(4)
f( - 4) = 2 + 12
f( - 4) = 14

If x+a is a factor of 2x²+2ax+5x+10,find a.
vazorg [7]

If x+a is a factor of the polynomial, it means that -a is a root of the polynomial.

In fact, if a polynomial p(x) has a root x_0 (i.e. p(x_0)=0), then the polynomial is divisible by (x-x_0)

In your case, you know that the polynomial is divisible by (x+a)=(x-(-a)), so -a is a solution.

Let's evaluate p(-a) and set it to zero:

2(-a)^2+2a(-a)+5(-a)+10 = 0 \iff 2a^2-2a^2-5a+10=0 \iff -5a+10 = 0 \iff a = 2

We can check the answer: if a=2 the polynomial becomes

2x^2+2(2)x+5x+10 = 2x^2+9x+10

And we're claiming that -a=-2 is a root of this polynomial:

2(-2)^2+9(-2)+10 = 2\cdot 4 - 18 + 10 = 0

Find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)
boyakko [2]
452.16 = 3.1416 r^2
r^2 = 452.16  /  3.1416
r^2 = 143.93
r = 11.997

C = 2 (3.1416) (12) =75.38 m
