The value of p if the pair of equations may have one root common is 1.
<h3>What are the
roots of the equation?</h3>
Let the equation be ax² + bx + c = 0.
Then the roots of the equation will be
The equations are given below.
2x² + px - 1 = 0 and 3x² - 2x - 5 = 0
The roots of the equation 3x² - 2x - 5 = 0 will be
3x² - 5x + 3x - 5 = 0
(3x - 5)(x + 1) = 0
x = -1, 5/3
At x = -1, the value of p will be
2(-1)² + p(-1) - 1 = 0
2 - p - 1 = 0
p = 1
The value of p if the pair of equations may have one root common is 1.

hopefully these are right
Step-by-step explanation:
Answer:
y = 0, -4
Step-by-step explanation:
1) Factor out the common term 3y.
2) Solve for y.
<em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>0</u></em><em><u>,</u></em><em><u> </u></em><em><u>-4</u></em>
<em><u>Therefor</u></em><em><u>,</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>0</u></em><em><u>,</u></em><em><u> </u></em><em><u>-4</u></em><em><u>.</u></em>
The answer is 810
23*2.5=57.5
57.5*12=690
690+120=810
