Solve the equation using the quadratic formula.

BabaBlast [244]

The value of x is -9 and 3.Option D.

Step-by-step explanation:

Given,

$-x^{2} +27 = 6x$

To find the value of x.

We will apply middle term factor formula.

The given equation can be written as,

$x^{2} +6x-27 = 0$

or, $x^{2}$ +(9-3)x-27 = 0

or, x²+9x-3x-27= 0

or, x(x+9)-3(x+9)=0

or, (x+9)(x-3) = 0

So, x = -9 and x = 3

Hence,

The correct option is Option D.

The parabola $y = ax^2 + bx + c$ is graphed below. Find $a+b+c$. (The grid lines are one unit apart.)

Ann [662]

If $x=0$ , then $y=a\cdot0^2+b\cdot0+c=5$ , so $c=5$ .

If $x=1$ , then $y=a\cdot1^2+b\cdot1+c=2$ , so $a+b+5=2$ or $a+b=-3$ .

If $x=2$ , then $y=a\cdot2^2+b\cdot2+c=1$ , so $4a+2b+5=1$ or $2a+b=-2$ .

We have

$a+b=-3\implies -a-b=3$

$(2a+b)+(-a-b)=-2+3$

$\implies a=1\implies b=-4$

So we end up with

$a+b+c=1+(-4)+5=\boxed{2}$
