Answer:
x= 0.348 OR X= -1.148
Step-by-step explanation:
Given that:
2x^2+8+3x^2+4x-10
The first step is to rearrange the parameters given, by doing so, we have:
= 2x^2 +3x^2 +4x -10+8
= 5x^2 +4x - 2
The above equation forms the basis of a quadratic equation;
So using quadratic formula
= (-b +/- (√b^2-4ac))/2a
= (-4 +/- (√4^2 -4*5*(-2))/2*5
= -4 +/- (√ 16 - (-40))/10
=( -4 +/- √ 56 ) / 10
=( -4 +√ 56 ) / 10 OR =( -4 - √ 56 ) / 10
= (-4 + 7.48)/10 OR (-4 -7.48)/10
= 3.48/10 OR -11.48/10
= 0.348 OR. -1.148
SO, x= 0.348 OR X= -1.148
Answer:
m = 5
Step-by-step explanation:
5 - 2 * (m - 3) = 1
5 - 2m + 6 = 1
-2m + 11 = 1
-2m = -10
2m = 10
m = 5
