$ax^2+bx+c=a(x-\alpha)(x-\beta)=a(x^2-(\alpha + \beta)x+\alpha \cdot \beta)\\\\\text{So we can say that:}\\\\\alpha + \beta = \dfrac{-b}{a}\\\\\alpha \cdot \beta=\dfrac{c}{a}\\\\\text{So the expected quadratic equation is}\\\\(x+\dfrac{b}{a})(x-\dfrac{c}{a})=0\\\\ \Large \boxed{\sf \bf \ (ax+b)(ax-c)=0 \ }$

Thank you

you deposit $6,700 in a money market account that pays an annual interest of 3.3% the interest is compounded quarterly how much

Rufina [12.5K]

so it is compounded 4 times in a year in 4 years we can take it as 16 terms

a=6700(1+3.3/100)^16

a=6700(1+33/1000)^16

a=6700(1000/1000 + 33/1000)^16

a=6700(1.033)^16

a=6700*1.681144887891022

a=6700*1.6811

a=11263.23
