Find distance between the points R(a+b,a-b) s(a-b,-a-b) |
|
Answer» We have to find the distance between the points\xa0R(a + b ,a - b) and S(a - b, - a - b).Using distance formula, we obtainRS =\xa0{tex}\\sqrt { ( a - b - a - b ) ^ { 2 } + ( - a - b - a + b ) ^ { 2 } }{/tex}=\xa0{tex}\\sqrt { 4 b ^ { 2 } + 4 a ^ { 2 } } = 2 \\sqrt { a ^ { 2 } + b ^ { 2 } }{/tex} what is the number (s) of zeros that a quadratic polynomial has/have |
