<h2>
x²+7x-2 = 0</h2>
Step-by-step explanation:
The general form of a quadratic equation with roots a and b is expressed as shown;
x²-(sum of root) x + (product of roots) = 0
x² - (a+b)x + ab = 0 ... 1
Given the sum of roots a+b = -7
Product of roots ab = -2
Substituting this values in equation 1 above wil give;
x²-(-7)x+(-2) = 0
x²+7x-2 = 0
The resulting quadratic polynomial is x²+7x-2 = 0

hey iif ram hari n shyam invest then the ratio shall be like x:y:z but the qstn isnot . ram:hari:shyam =? it can't be 4:5 only it might be 4:5:?
2a + 3p = 1.59
a = 0.24
Plug it in our equation:
2(0.24) + 3p = 1.59
Multiply:
0.48 + 3p = 1.59
Subtract 0.48 to both sides:
3p = 1.11
Divide 3 to both sides:
p = 0.37
So one pair costs <span>£0.37</span>
