GaryK [48]

Answer:

a = 15/2

Step-by-step explanation:

3a−15=4a−3a

Combine like terms

3a - 15 = a

Subtract 3a from each side

3a-3a−15=a−3a

-15 = -2a

Divide each side by -2

-15/-2 = -2a/-2

15/2 =a

PLEASE HELP!!!!!!!!!

Let $x_1 , x_2$ be the roots of the equation $3x^2-5x-7$ . By the Viet theorem you have that $\left \{ {{x_1+x_2=- \frac{5}{3} } \atop {x_1x_2= \frac{-7}{3} }} \right.$ .

For the equation $x^2+bx+c = 0$ you'll have that $c=(x_1+2)(x_2+2)=x_1x_2+2(x_1+x_2)+4=\frac{-7}{3}+2\cdot(- \frac{5}{3} )+4$
That is $\frac{-7}{3}- \frac{10}{3} +4=- \frac{5}{3}$ .

Answer: $- \frac{5}{3}$
