Solution

To find the values of a for which the equation (a − 3)x^2 + 2ax + (a + 2) = 0 has no solutions for x, we can use the discriminant of the quadratic equation.

The discriminant is given by the formula Δ = b^2 - 4ac, where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c = 0.

In this case, the coefficients are: a = (a - 3) b = 2a c = (a + 2)

Substituting these values into the discriminant formula, we have: Δ = (2a)^2 - 4(a - 3)(a + 2)

Expanding and simplifying, we get: Δ = 4a^2 - 4(a^2 - a - 6)

Further simplifying, we have: Δ = 4a^2 - 4a^2 + 4a + 24

Combining like terms, we get: Δ = 4a + 24

For the equation to have no solutions, the discriminant Δ must be negative. Therefore, we have the inequality: 4a + 24 < 0

Solving this inequality, we subtract 24 from both sides: 4a < -24

Then, dividing both sides by 4, we get: a < -6

Therefore, the values of a for which the equation has no solutions for x are all values less than -6.
