x2 - 15x +54=0

x2-(9+6)x + 6×9=0

x2 -9x-6x+54=0

x(x-9)-6(x-9)=0

(x-9)(x-6)=0

This implies :x=either 6 or 9

Answer:


Step-by-step explanation:3x + y =10⇒1×9

                                            9x+py=23⇒2×3

                                             ⇒27x +9y =9

                                               - 27x + 3py = 46∴by sub 1 and 2

                                                 0 + 6py =37⇒

                                                     y=  37÷6p⇒sub in 1

                                                   3x + y = 10⇒3x + 37÷6p = 10 ⇒3x + 37                        =60p
