Question

3. Write the following equations in the form ar? + bx + c = 0, then write the value

a, b, c for each equation.

(3) x2 + 5x = -(3 - x)
​

Answer 1

Answer:

a, b, c for each equation.

(1) 2y =10 - y2

(2) (x - 1)2 = 2 x + 3 (3) x² + 5x = -(3 - x)

(4) 3m2 = 2 m² - 9 (5) P (3 + 6p) = -5 (6) x2 - 9 = 13

4. Determine whether the values given against each of the quadratic equation are th

roots of the equation.

(1) x² + 4x - 5 =0, x= 1, - 1 (2) 2m2 - 5m = 0, m = 2, 3

5. Find k if x = 3 is a root of equation kx2 - 10x + 3 = 0.

6. One of the roots of equation 5m² + 2m + k = 0 is 5. Complete the following activ

to find the value of ’k”.

lir a root of quadratis equation 5m2 + 2m + k = 0

Answer 2

Step-by-step explanation:

x2 + 5x + x -3 = 0

x2 + 6x -3 = 0

a = 1

b = 6

c. = -3
