Firstly, begin by multiplying both sides of the equation by (x-2) and (x+3), this gives 6(x+3)-2(x-2)=(x+3)(x-2). Expand out the brackets on each side of the equation to give 6x+18-2x+4=x2-2x+3...
(1) x2 + 15x + 56 = 0
56 = 1 x 56, 2 x 26, 4 x 14, 7 x 8
7 + 8 = 15
Hence, factorised equation is (x + 7)(x + 8) = 0
First we have 0.03 x 10.1, multiply without decimal points: 3 x 101 = 303
Since there are 2 decimal places 0.03 and 10.1 has 1 decimal pla...
First we add up all the 'x' terms. So the equation 7 - 4x = x + 8 becomes 7 - 4x - x = x +8 - x => 7 - 5x = 8. Now we can do the same with the ot...
First, expand (x-2)2:
= (x-2)(x-2),
= x2 - 2x - 2x + 4
= x2 - 4x + 4
Add on the +7:
= x2 - 4x + 11
