the equation -2x^2+3=-9x is rewritten in the form of -2(x-p)^2 +q=0. What is the value of q?the equation -2x^2+3=-9x is rewritte
Novosadov [1.4K]

Value of q is \frac{105}{8} .

<u>Step-by-step explanation:</u>

We have , the equation -2x^2+3=-9x is rewritten in the form of -2(x-p)^2 +q=0 . We need to find What is the value of q . Let's find out:

Let's simplify equation -2x^2+3=-9x into -2(x-p)^2 +q=0 :

⇒ -2x^2+3=-9x

⇒ -2x^2+9x+3=0

⇒ 2x^2-9x=3

⇒ 2(x^2-\frac{9}{2}x)=3

⇒ (x^2-\frac{9}{2}x)=\frac{3}{2}

⇒ (x^2-2(1)\frac{9}{4}x)=\frac{3}{2}

⇒ (x^2-2(1)\frac{9}{4}x) + (\frac{9}{4})^2=\frac{3}{2} + (\frac{9}{4})^2

⇒ (x-\frac{9}{4})^2=\frac{3}{2} + (\frac{81}{16})

⇒ (x-\frac{9}{4})^2=\frac{24}{16} + (\frac{81}{16})

⇒ (x-\frac{9}{4})^2=\frac{105}{16}

⇒ -2(x-\frac{9}{4})^2=-2(\frac{105}{16})

⇒ -2(x-\frac{9}{4})^2=-\frac{105}{8}

⇒ -2(x-\frac{9}{4})^2+\frac{105}{8} = 0

Comparing this equation to -2(x-p)^2 +q=0 , q =\frac{105}{8} .

Therefore ,Value of q is \frac{105}{8} .

Please help on this question.
Sonbull [250]

Answer:

C

Step-by-step explanation:

\frac{ - 20 {x}^{2}  + 14x + 12}{5x - 6}  \\  \\  =   \frac{- (20 {x}^{2}   - 14x - 12)}{5x - 6}  \\  \\ =   \frac{ - (5x - 6)(4x + 2)}{5x - 6}  \\  \\  =  - (4x + 2 ) \\  =  - 4x - 2

Domain:

g(x) ≠ 0

5x - 6 = 0 \\ 5x = 6 \\  \\ x =  \frac{6}{5}

All real numbers ≠ 6/5
