Question

Exercise 1.5
1..
2. Solve 18 x2 - 3x = 6
3. Solve 50 x? - 72 = 0
4. Solvex(2x - 1) = 3
5. Solve (x + 3)(x - 5) = -7
6. Solve r? - x - 12 = 0
7. Rewrite the following quadratic equations in factoring forms
a) x? - x - 20 = 0
b) 2x2 + 3x - 5 = 0​

Answer 1

2) 36-3x = 6

36-6 = -3x

30 = -3x

-10 = x

5) xsq+ 3x -5x -15

xsq -2x -15

Hope this helps you
