Answer:

m = 3

n = 14

p = 2

Step-by-step explanation:

Given:

\frac{7}{x}-\frac{3}{2}=\frac{n-mx}{px}

We need to find the values of m, n, p

Solution:

We will first solve the L.H.S

L.H.S = \frac{7}{x}-\frac{3}{2}

Now we will first make the denominator common by taking L.C.M

=\frac{7\times 2}{x\times 2}-\frac{3\timesx}{2\timesx}\\\\= \frac{14}{2x}-\frac{3x}{2x}

Now the denominator is common hence we will subtract the numerators.

L.H.S = \frac{14-3x}{2x}

Now Comparing the the value of L.H.S with R.H.S we can say that;

\frac{14-3x}{2x}=\frac{n-mx}{px}

m = 3

n = 14

p = 2

Answer:

x= -2-√11. or. x= -2 + √11

Step-by-step explanation:

solving quadratic equation by completing the square

x^2+4x-7=0

x^2+4x=7

x^2+4x + (4/2)^2=7 + (4/2)^2 ( adding (1/2 coefficient of x)^2 on both sides

x^2+4x + 4=7 + 4

x^2+4x + 4=11. factorize(x^2+4x + 4) into (x + 2)^2

(x + 2)^2=11

√(x + 2)^2= + - √11

x + 2 = + - √11

there are two different solution .

x + 2 = -√11. or x + 2 = + √11.

x= -2-√11. or. x= -2 + √11.

h=-16t^2+36t+4\implies \stackrel{h}{0}=4(-4t^2+9t+1)\implies 0=-4t^2+9t+1 \\\\[-0.35em] ~\dotfill\\\\ ~~~~~~~~~~~~\textit{quadratic formula} \\\\ 0=\stackrel{\stackrel{a}{\downarrow }}{-4}t^2\stackrel{\stackrel{b}{\downarrow }}{+9}t\stackrel{\stackrel{c}{\downarrow }}{+1} \qquad \qquad t= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a}

t= \cfrac{ - (9) \pm \sqrt { (9)^2 -4(-4)(1)}}{2(-4)} \implies t = \cfrac{ -9 \pm \sqrt { 81 +16}}{ -8 } \\\\\\ t= \cfrac{ -9 \pm \sqrt { 97 }}{ -8 }\implies t=\cfrac{9\mp\sqrt{97}}{8}
