To solve the equation 1 + 7x + 10x^2, we can use the quadratic formula.
The quadratic formula is given by:
x = (-b ± √(b^2 - 4ac)) / (2a)
Comparing the given equation to the standard quadratic form ax^2 + bx + c = 0, we have:
a = 10, b = 7, c = 1.
Plugging these values into the quadratic formula, we get:
x = (-7 ± √(7^2 - 4*10*1)) / (2*10)
Simplifying this expression further, we get:
x = (-7 ± √(49 - 40)) / 20
x = (-7 ± √9) / 20
x = (-7 ± 3) / 20
Solving for both values, we have:
x = (-7 + 3) / 20 = -4/20 = -1/5
x = (-7 - 3) / 20 = -10/20 = -1/2
So, the solutions to the equation 1 + 7x + 10x^2 = 0 are x = -1/5 and x = -1/2.
