4. (i) Solve the equation 2x2 – 7x + 4 = 0, giving your answers correct to 2 decimal places.

(ii) Hence, find the values of y that satisfy the
equation 2(y – 1)2 – 7(y – 1) + 4 = 0.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
