If I'm not wrong, you must draw a graph for this y=-2x +2 sub x=-1 ,0 and 1 and do the same for y=x^2-3x and plot the coordinates don't worry y=-2x+2 will be a straight line because it's x is to the power of one and **to find the no. of solutions, refer to ur graph and count the number of point of intersections and that will be ur answer Hope this helps :)
6 x 89 is 534 6 x (90 - 1) is 534. BUT you have to subtract 90 from 1 and that's 89. So then you multiply 6 by 89. 6 x 90 is 540 and 6 x 1 is 6. you take 540 subtract 6 and that's 534. 540 - 6 is 534.
