X = math
y = history
x + y = 248
x + x - 68 = 248
2x = 316
x = 158
y = 90
There were 158 math textbooks sold and 90 history textbooks sold.

Use the quadratic formula to solve the equation if necessary round to the nearest hundredth x^2+x-30=0

yaroslaw [1]

Answer:

(x-5)(x+6)=0

Step-by-step explanation:

hehe i doing the smae unit rn.

if a=1 (which it does do ac factoring)

you need two numbers that multiply to -30 and add to 1. those numbers are 5 and -6.

substitute 1x for -5x + 6x.

group the numbers into pairs and find their gcf's

x(x-5) 6(x-5)

since the parenthesis r the same yo only need one. Now you need to put x and 6 in a parenthesis.

FINAL: (x-5)(x+6) hope this helps
