Answer:
x =(14-√340)/8=(7-√ 85 )/4= -0.555
or
x =(14+√340)/8=(7+√ 85 )/4= 4.055
Step-by-step explanation:
step 1 :
(22x2 - 14x) - 9 = 0
Step 2 :2.1 Factoring 4x2-14x-9
The first term is, 4x2 its coefficient is 4 .
The middle term is, -14x its coefficient is -14 .
The last term, "the constant", is -9
