Two angles are supplementary. One angle can be represented by 2x, while the other by 3x-10. What is the value of 2x? Based on th

liubo4ka [24]

Supplementary angles = 180
2x +3x-10 = 180
5x -10 =180
5x -10 +10 =180+10
5x =190
5x/5 =190/5
x = 38
2x=76
3x-10= 3(38)-10=104

The measure of angles are 76 and 104

Find a formula for the product P of the solutions of the quadratic equation ax²+bx+c=0 .

Ede4ka [16]

Answer:

product of the roots= c/a

Step-by-step explanation:

The the two roots(α and β) of the quadratic equation ax²+bx+c=0 as given by shridharacharya formula are

$\alpha= \frac{-b+\sqrt{b^2-4ac} }{2a}$

$\beta= \frac{-b-\sqrt{b^2-4ac} }{2a}$

now product of the roots

αβ= $\frac{-b+\sqrt{b^2-4ac} }{2a}$ × $\frac{-b-\sqrt{b^2-4ac} }{2a}$

use formula (a+b)(a-b)= a^2-b^2 and solve we get

αβ= c/a

therefore product of the roots= c/a
