Question

Math question 2 ) 2ײ+ 7 × - 9 = 0​

Answer 1

Answer:

2xsq+9x-2x-9

x(2x+9)-1(2x+9)

x-1(2x+9)

x=1 and x=9/2

Answer 2

Step-by-step explanation:

2x² +7x -9 = 0 -9 × 2x²= -18x²

2x² -2x+9x -9=0

2x(x-1) +9(x-1)=0 -18x²=+9x × -2x

(2x+9) (x-1) = 0

2x+9=0 or x-1 =0

2x= -9 or x= 1

x= -9/2 or x= 1
