解析 You getx= (-b± √ (b^2-4ac))(2a)= (-(5)±√ ((5)^2-4(1)(-3)))(2(1))= (-5± √ (37))2=- 52± (√ (37))2The solution of the equation x^2+5x-3=0 is x such thatx=- 52± (√ (37))2.反馈 收藏 ...
Use the quadratic formula to solve the quadratic equation: {eq}33 = 8c + c^2 {/eq} The Quadratic Formula: The quadratic formula is a method used in solving quadratic equations in the form {eq}ax^2+bx+c=0 {/eq} where {eq}a {/eq} and {eq}b {/eq} are coefficients...
The quadratic formula is a formula that we use to solve quadratic equations. It states that if ax2 + bx + c = 0, then {eq}x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a} {/eq}. This formula comes in quite handy in solving quadratic equations, as the process just takes a few ...
