Algebra calculator is a fast and easy math tool that solves equations, simplifies expressions, and shows step-by-step solutions. The quadratic equation calculator is useful for students and homework help.
x1 = -1.03
x2 = 0.97
Equation: 2x+5=15x^2+3x-10
Simplified equation: -15x² - x + 15 = 0
Quadratic formula:
x = [−b ± √(b² − 4ac)] / (2a)
Here: a=-15, b=-1, c=15
D = b² - 4ac = 901 > 0
Two real solutions:
x = [1 ± √901] / -30
x1 = (1 + 30.02) / -30 = 31.02/-30 = -1.03
x2 = (1 - 30.02) / -30 = -29.02/-30 = 0.97
