Explanation: x2 +4 = 0 subtract 4 on both sides to get. x2 − 3x − 4 = 0 x 2 - 3 x - 4 = 0. Take square root of both sides to have x+ #3/2# = #5/2# or #-5/2# x+ #3/2# = #5/2# would give x= #5/2#-#3/2# = 1 and . x = 0 x = 0. The quadratic formula gives us solutions: x = (-b+-sqrt(b^2-4ac))/(2a) =(3+-sqrt(3^2-(4xx1xx-4)))/(2*1) =(3+-sqrt(9+16))/2 =(3+-sqrt(25))/2 =(3+-sqrt(5^2))/2 =(3+-5)/2 That is x=-1 or x=4 Find an answer to your question What are all the solutions of x2 + 3x - 4 = 0? What are all the solutions of x2 + 3x - 4 = 0? - brainly. In this case, whose product is −4 - 4 and whose sum is −3 - 3. x(x −3) = 0.541 x = (-3+√37)/2= 1. 100. Integration. Factor out the greatest common factor from each group. 2 2 2 3 4. Add 4 4 to both sides of the equation. x=1 , -4 Take half of the coefficient of x, that would be #3/2# in this case. x2 − 3x − 4 x 2 - 3 x - 4. The discriminants of a quadratic equation a x 2 + b x + c = 0 is given by: D = b 2-4 a c. Enter a problem Cooking Calculators. Try this example now! » Algebra.
