\\ \rm\Rrightarrow 5-3(2a+1)=-4+10

\\ \rm\Rrightarrow 5-6a-3=6

\\ \rm\Rrightarrow -6a+2=6

\\ \rm\Rrightarrow -6a=6-2

\\ \rm\Rrightarrow -6a=4

\\ \rm\Rrightarrow a=\dfrac{4}{-6}

\\ \rm\Rrightarrow a=\dfrac{2}{-3}

Now

\\ \rm\Rrightarrow a+2

\\ \rm\Rrightarrow \dfrac{2}{-3}+2

\\ \rm\Rrightarrow \dfrac{2-6}{-3}

\\ \rm\Rrightarrow \dfrac{-4}{-3}

\\ \rm\Rrightarrow \dfrac{4}{3}

Answer:

7/3

Step-by-step explanation:

5 - 3(2a+1) = -4 + 10

=> 5 - 6a + 3 = 6

=> 5 - 6 + 3 = 6a

=> 2 = 6a

=> 6a = 2

=> a = 2/6

=> a = 1/3

a + 2

1/3 + 2

=> 1/3 + 6/3

=> 7/3

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
