When rounding to 2dp, you look at the third digit after the decimal. If it is 5 or larger, you round the second digit up, if it is less than 5, you round it down.

Answer:

$\fbox {x-intercepts : (1, 0) and (-3, 0)}$

$\fbox {Roots : x = 1, x = -3}$

Step-by-step explanation:

Given :

y = 4x² + 8x - 12

4 cancels throughout.

y = x² + 2x - 4

Solving by quadratic formula :

x = -8 ± √(8)² - 4(4)(-12) / 8
x = -8 ± √64 + 192 / 8
x = -8 ± √256 / 8
x = -8 ± 16 / 8
x = -1 ± 2
x = 1 and x = -3

∴ Hence, the x-intercepts are (1, 0) and (-3, 0). The roots of the equation are 1 and -3.
