The solution to the equations are:
- 9x² - 36x + 36 = 0 has two equal real solutions
- x² - x + 4 = 0 has no real solutions
- The factored expression of 4x² + 23 – 35 is 4(x² -3)
Part A: Describe the solution
The equation is given as:
9x² - 36x + 36 = 0
The above equation is a quadratic equation which can be represented as:
ax² + bx + c = 0
The discriminant (d) is calculated as:
d = b² - 4ac
So, we have:
d = (-36)² - 4 * 9 * 36
d = 0
A discriminant of 0 means that the equation has two equal real solutions
Hence, 9x² - 36x + 36 = 0 has two equal real solutions
Part B: Describe the solution
The equation is given as:
x² - x + 4 = 0
The above equation can be represented as:
ax² + bx + c = 0
The discriminant (d) is calculated as:
d = b² - 4ac
So, we have:
d = (-1)² - 4 * 1 * 4
d = -15
A discriminant of -15 means that the equation has no real solutions
Hence, x² - x + 4 = 0 has no real solutions
Part C: The solution to the expression
We have:
4x² + 23 – 35
Evaluate the difference
4x² -12
Factor out 4
4(x² -3)
Hence, the factored expression of 4x² + 23 – 35 is 4(x² -3)
