A quadratic function can always be factorized, but the factorization process may be difficult if the zeroes of the expression are non-integer real numbers or non-real numbers. In such cases, we can use the quadratic formula to determine the zeroes of the expression. The general form of a qu...

Quadratic Formula:x = −b ±√(b2 − 4ac) 2a Put in a, b and c:x = −6 ±√(62 − 4×5×1) 2×5 Solve:x = −6 ±√(36− 20) 10 x = −6 ±√(16) 10 x = −6 ± 4 10 x = −0.2 or −1 And we see them on this graph. Answer: x =...
The quadratic equation formula to solve the equation ax2+ bx + c = 0 is x = [-b ±√(b2- 4ac)]/2a. Here we obtain the two values of x, by applying the plus and minus symbols in this formula. Hence the two possible values of x are [-b + √(b2- 4ac)]/2a, and [-b -...

We can now represent the function as: (x−1)(x−0.75)and this, when multiplied out, gives x2 − 1.75x + 0.76 and which when multiplied by 4 gives the original equation 4x2 − 7x + 3. (b) Using the general quadratic formula [10] gives: x=−2±16−162=2Therefore, we ...
