Write the following equations in the form ax2 + bx + c = 0, then write the values of a, b, c for each
i. 2y = 10 – y2
ii. (x – 1)2 = 2x + 3
iii. x2 + 5x = – (3 – x)
Write the following equations in the form ax2 + bx + c = 0, then write the values of a, b, c for each
i. 2y = 10 – y2
ii. (x – 1)2 = 2x + 3
iii. x2 + 5x = – (3 – x)
i. 2y – 10 – y2
∴ y2 + 2y – 10 = 0
Comparing the above equation with
ay2 + by + c = 0, we get
a = 1, b = 2, c = -10
ii. (x – 1)2 = 2x + 3
∴ x2 – 2x + 12x + 3
x2 – 2x + 1 – 2x – 30
∴ x2 – 4x – 2 = 0
Comparing the above equation with
ax2 + bx + c = 0, we get
a = 1, b = -4, c = -2
iii. x2 + 5x = – (3 – x)
∴ x2 + 5x = -3 + x
∴ x2 + 5x – x + 3 = 0
∴ x2 + 4x + 3 = 0
Comparing the above equation with
ax2 + bx + c = 0, we get
a = 1, b = 4, c = 3
