Factors are (2x + 1)(x + 4), making x either -0.5 or -0.25
2x2+5x-3 = 0 (2x-1)(x+3) = 0 x = 1/2 or x -3
2x2 + 11x + 15 = (x + 3)(2x + 5).
-7
Reading this as: 4x2-6=2x2 This implies that: -6=-2x2 3=x2 x=sqrt(3) and x=-sqrt(3) So x can equal plus or minus the square root of 3
What is the solution set of 2x2 + x = 15
2x2 equals 5
3
2x2-7x+3 = 0 (2x-1)(x-3) = 0 x = 1/2 or x = 3
Factors are (2x + 1)(x + 4), making x either -0.5 or -0.25
2x2+5x-3 = 0 (2x-1)(x+3) = 0 x = 1/2 or x -3
2x2 + 11x + 15 = (x + 3)(2x + 5).
8 - 2x2 = x + 22 - 7Combine like terms on the right side:8 - 2x2 = x + 15Subtract 8 from each side:-2x2 = x + 7Add 2x2 to each side:0 = 2x2 + x + 7
It can't be solved because its discriminant is less than zero
